Hide Certain Music Files

Hey i have downloaded the Gps Navi/Cop Tracker app "Waze V. 1.8" and I think once this app catches on and there are more users it will be a fantastic application.. especially with future releases making it run smoother...
This is a turn by turn navi, so basically it saved all the "sounds" from that app onto my storage card... Unfortunately this makes the sounds show up in my Sense Music player... This is something that i simply cannot allow...
My question is there a way where i can make all those music files hidden?? so that they don't show up in the music player anymore?? i remember i did something along those lines with a wallpaper picture... i had to use a registry editor and i changed the properties of that photo to hidden.. and then it didn't show up on my albums anymore.. Has anyone sucessfully done what i am talking about?? or am i the only person who downloaded waze... or i'm the only person that has an issue with the app sounds showing up in my music folder... and i honestly don't want to make a playlist either and not include the sounds...i have one library of music.. and i play all of them.. no playlists.. ever...
sp yea.. i'm sure you guys by now, get a handle on what i'm talking about and what i'm seeking to accomplish.. so any help would be greatly appreciated... any tips, suggestions or workarounds.. thanks guys

+1 on that, Music Player lists all my Ringtones which I don't want to be listed there.

Your post has just made me realize where all those mp3's have come from.
Having recently installed Waze, I hadn't noticed them until I installed the recent HTC Music Player update and assumed that had caused all the unwanted files to show up in the player.
Having looked a little closer at the offending files, they are definitely from the Waze install.
I have co-pilot installed on my SD card but none of it's sound files show up in the music player. I'm assuming they are also mp3's and if so how do they remain hidden and the Waze files are not??

I used Total Commander to go to Program Files> Waze > Sound

Next tick the Hidden System and Change check boxes and click the Now button.
Waze sound files no longer show in the Music player!

bravo my good friend... the dumb thing is... i actually already had tried that.... but nothing happened so i gave up and came running here... but after seeing your success .. i went and tried again... same thing... nothing happened... i had to do a soft reset first... and the. they were no longer in my music player... totally rocks bro lol nice

Good to hear you are now sorted.
Oddly I didn't need to soft reset, but as long as you get the end result it's all good

I tried this method after installing the HTC Music update, but now it takes over 30 seconds for music to open and show the now playing screen with the album covers.
For the first three times i tried to open Music, I kept getting a "filesys.exe" error, tried to send the error report and the phone froze (like it always does when I try to send any report) so i had to soft reset about 4 times in a row.
Now it plays but is really slow and laggy.
None of this happened when i had all my tunes as individual tracks, no folders! All i wanted to do was get rid of the Waze sounds files and now i can't even play any music!!

Did hiding the folder affect the voice turn by turn? Waze especially?
Edit: I did my own testing. Hiding the sounds folder in Waze did not affect voice turn by turn so if you have Waze, go ahead and hide those annoying sounds which appears in the music folder.
For the ringtones, if you don't have many, I suggest putting them in \Windows\Rings and for alerts put them in \Windows. This is because the music player sees the tones if you put them in \My Documents\My Ringtones (and as the previous poster found out, hiding them makes them inaccessible to all programs.

I tried hiding a folder I had on my storage card that contained my ringtones: whilst it hid them from the music player (once it rescanned), it also meant that the phone was unable to see the ringtones and thus failed to list them in the ringtone lists.
I gave up trying to find a registry setting for it and just changed the ID3 tags for all ringtones to say that they were by an artist called 'ringtone' in an album called 'ringtone'.
Contacting HTC Support suggested I create a playlist with all the songs I want in it -___-

same problem here, I need them as ringtones so hiding them is not an option
btw how can I add the music player to my startup list so it scans for the music when the phone starts? I can't remember the name of the file that was doing that, read it here somewhere but can't find it anymore :/

Google Play Music - library not showing up

I cannot get my mp3's to show up in Google Play Music. The are under /storage/emulated/0/Music. I have one song under the Music folder and another folder under Music.
I have wiped data for the app and uninstalled and reinstalled the app.
What am I doing wrong?
Thanks

Did you get your issue resolved. My downloaded music will not show up as well.

Downloaded music doesn't appear in a public folder like that - it's in the app's data folder, partially encrypted (meaning filenames are obfuscated, but play fine once copied).

No I didn't. I just figured I was stupid or something.
I have my music under a folder called Music. It's not buried under another folder. It worked on my Note 3 but not on this phone.

I've had this problem multiple times but can't quite recall how I fixed it. I think I went to settings>apps>options>show system>clear data for media storage and clear data for play music>reboot. If that doesn't work, use a root file explorer(assuming you have root) and look for a .nomedia file in your media directories.

Cleared media storage as well? Hmm. You could try xposed media scanner optimizer if you use xposed and really determined to try and fix this.

Yeah, several times.
I gave up and am using Music Folder Player.
I'm on Pure Nexus with no mods.

This was bothering me alot when I was heavy on adding/moving music in my subfolders under my Music folder. There are still some tracks I can't play.
I too tried the clear data clear cache uninstall reinstall etc etc. Sometimes it'll work sometimes it wont. I also took my tracks out of their subfolders and put it all in a general folder sometimes that would work too. Very annoying lol

Google Play Music won't find my music

Hello.
For a long time now I haven't been able to listen to any music at all from my phone. This hasn't really bothered me because I rarely use it for music. Now I just discovered this again and I can't let it go, I cannot just leave this. I am irritated, frustrated and it's annoying the hell out of me.
Google Play Music (or any music app) won't find my music! I have put it in different folders and locations but nothing helps. I can't find my downloaded music either through Google Play Music. When it's downloaded the app tells me it's stored locally somewhere and it works offline, so it's on my phone somewhere (I know Play Music stores them in numeric names).
The odd thing is though, if I set a music file as my ringtone, Play Music will find the song under "Unknown artists" and "Unknown Albums". THIS is what irritates me, why can't it just find my Music folder?
I've tried a lot of things;
Formatted my phone and reinstalled it (even stock won't find it)
Cleared Cache and Dalvik
Reinstalled the app(s)
Tried different formats (.ogg, .m4a, .mp3 for example)
Used apps to "Rescan" my internal storage (media finder)
I had this issue on my old Samsung device with CM10. On my N6P I'm currently running PureNexus 6.0.1-20160803-OFFICIAL.
Whoever can help me with this will be my hero, trust me, this is so freaking annoying I'm actually considering buying an iPhone............... Alright, that was a little too extreme, I would never do that. That's just the frustration inside me talking.

I created a folder called Music that is in a location accessible when I plug my phone into the computer. I have my music organized as follows--artist folder/album folder/songs. My songs are all mp3 format, which works on Android. I use a third party music player (Black Player currently, Shuttle Music Player previously).. The music player automatically finds the albums I stored. I don't think Google's Music App works as a music player for your own music. Are you ripping your own music or downloading it or what? Do your music files have meta-tags that allow a music player to identify what the music is?

I've bought my music and ripped it to my computer. All meta-tags are present so that shouldn't be an issue. Like I said, the weird part is, if I add a song as my ringtone Google play music finds it, but I don't want to do that for each and every song I have haha.

That would irritate me too!
It's weird that it has carried over on a clean flash. When you say your formatted the phone, did you also do the data partition? May be obvious, but the folder isn't hidden, is it? So the folder would be ".Music"? Or is there a file in there called ".nomedia"?

What music player are you using? I've had phones from HTC, Samsung, Motorola and Huawei and never experienced this problem. The fact that you had the exact same issue on 2 different phones suggests that you are doing something that is causing the problem, although its hard to see what. Your files aren't DRM protected if you are ripping them yourself. Maybe if you use a good third party music player it will find your music. I would stick to MP3 format on the files since that is compatible with Android. I had some files in Apple's format and had to convert them to MP3.

I've done a total clean format on my phone now, wiped everything including data/partition/storage. I have not done anything to the folder or renamed it. It's stilled called "Music" and there are no .nomedia files inside that specific folder (only in other folders that's not related at all).

Google Play Music (my music player)
What should I try? I tried PowerAmp or what it's called to see if it can locate my files but no success. The files are not DRM protected and I'm sticking to MP3 because like you said, higher probability it will find the files somehow.
I understand I might be the cause of this, and I don't mind it as long as I can understand what I'm doing xD As long as I know what's causing it I can let it go and remain peaceful, but as long as I have no idea what is causing this I will tear my hair off.

For it to persist across clean flashes and two different devices, there must be something in the folder that's buggering it up.
I would delete everything, then try copying some completely unrelated mp3's over to the same location to see if they're visible. If so, you know the problem is with the content. You can then go through this folder by folder until it stops working and you know what the culprit is.

I would try Black Player or Vanilla Music. Apparently you can use Google's app to play your own music but I'm not familiar with how that works. You do have a dedicated music folder called music, correct? What is the file path to your music folder? And how do you organize your music within that folder? Loose music tracks or folders for your artists and/or albums?

Then it must be the folder itself, as I've mentioned before I have already tried done a complete wipe of my internal storage to get it working but with no success. Can I change the path for android to search for my music?

Alright, so I downloaded BlackPlayer to try it out. It can't find any music files on my device at all. When I try to set a different search path (trying to select which folder the app should check for music) I can't even see my internal storage... This is really starting to worry me if my device might be faulty in some way (highly unlikely though because the device works perfectly fine with gallery and ES File explorer).
Within the Music folder I have it categorized in folders for example; /music/Children of bodom/Are you dead yet/ and then the songs from the album. I have also put some MP3 files directly into the Music folder to make sure the subfolders aren't messing with the apps.
So again, weird that BlackPlayer won't find any files at all and can't even recognize my internal storage. What can make this happen?
Edit: Just hit me, why don't I check the internal storage to see what's being used. In Settings>Storage & USB I can see that 1.08 GB worth of music is being used of my internal storage. When I click on it to see what files I have, I can only check something called "Unknown", inside that tab I have another folder called "Unknown" and inside THAT folder I can see my 3 custom ringtones..... What is going on?

You should check what the permissions are for your music folder. Root Explorer lets you check and change permissions for folders but costs 3.99. ES Explorer used to be good for this function as well but that program is a hot mess now. Do you have some kind of program on your phone that can check and change folder permissions? If Black Player can't find your music folder maybe read permissions aren't set properly for some reason.

I stopped using GPM a while ago. Such a battery hog and missing so many features. I use Sony music now. Has built in equalizer and album art finder. If u want to try it I can post the link

There's a flashable Zip that fixes file permissions on entire internal SD Card. Use the download link after the text, not the highlighted one within the text.

It might help. It sounds like the permissions on your internal storage might be screwy. I was hoping changing permissions on the single folder might fix it.

I tried that but it didn't work... Same issue persist. I've found out though that VLC can recognize my files (through the explorer that belongs to VLC). When I play one of my songs to my car stereo through VLC the display say "fd://34" in the song title... What could this mean? The numbers change depending on the track, one is called fd://34 and the next one might be called fd://53 etc.

Blackplayer doesn't work either and I want to use Google Play Music since I've bought a couple of songs from them. Don't want to switch between different music apps. I also like Google Play Music the most out the majority of apps.

Are you sure your music tracks have proper metainformation? It sounds like VLC can't tell what any of your music is and is using a generic placeholder name. I would open some of your music on your computer with the free program Mp3tag and verify that information shows up in the title/artist/album fields. If the fields are blank then your music isn't tagged properly. You can also right click on a music file and go to the details tab but I prefer the Mp3tag program because if something is wrong it's easy to do the tags for an entire album at once. You didn't do anything unusual with the formatting of your data partition on the phone?

I've checked the metatags and it's all fine. Everything is there.
I thought so as well about the VLC thing. But yet again, with all the metatags there, how come it can't recognize anything? Seems so weird.
No, I don't think I did. I'm using TWRP right now and I do a clean wipe using the options inside that. Before TWRP I used CWM, same issue persisted though. I appreciate your help so much, I'm trying my best here to figure it out but it helps a lot with your ideas! Just like to say that so I don't seem ungrateful

Unknown Artists Problem After Upgrading to Android 7.0 Nougat on Moto G4 Plus

I've recently updated my Moto G4 Plus to Android 7.0 Nougat. But a problem arose after updating and it's annoying me. Most of my music lost some information like album art, artist name, track duration, and title after copying them to my SD card. The weird thing is, they play fine.
Not all of them lost information but many of them did. The tracks that lost information show durations of 0:00 but then again, they play fine. This happens to all of my music players on my phone. (Phonograph, Google Play Music)
Here is another weird thing. When opening the music in a tag editor, the info finally shows up correctly (Album art, track info, duration, and all) but out of that, even I save it, the same problem occurs.
I have tried:
-Rebooting device
-Recopying music from PC to SD card
-Force closing music player apps
-Clearing data and cache from music player apps
-Editing them on a tag editor and saving them
-Removing and putting back SD card from slot
-Using ID3Fixer
-Deleting (com.android.providers.media) folder and rebooting
-Clearing cache partition

Try clearing data in Media Storage (com.android.providers.media). Then reboot.

Try This
Is simple to solve, look at the TagScanner program, download and install it. Copy all your songs to the pc and open them in the program, note that the songs that are presenting the error are with album covers in png format and / or very large sizes (the ideal for the android is 600x600).
Change the png covers by jpg, and before moving to the phone again, force stop and clear the app data "media storage", restart the device and pass the songs to it. Apparently the android has an incompatibility with album covers at very high resolutions, so this bug happens.
Sorry for the bad English.

If that's the case, then why are my other songs with large album arts fine? Again, the problem didn't apply to all of my music. My other albums with 1000x1000 or more still show up the way they did before. Also, this is only happening to my current phone. When the files were in my old one, they didn't have these problems. (See attached screenshot)

Dude, I do not know how to explain what really happens. Just noticed that Android does not recognize the PNG format if it is over 600x600 in size, JPEG may be up to it to recognize in large sizes, but not PNG. Try switching the covers of the songs that are with the bug to a 1000x1000 resolution JPEG version.:good:

Happens with me sometime. For me, i simply copy the music files to other NEW FOLDER. & It got fixed. To be more sure just open ES Explorer & navigate to the music folder, it might show up the album art. Try once.

I know this is late but I've discovered the reason. I now know what's causing the problem. For those who still use Moto G4 Plus to this day (or any other phone with the same problem), chances are it's because Android Nougat(?) doesn't support music files with cover art/album covers greater than 1 MB. It's not about the resolution, although it's what was observed by a user above. It's actually the image file size causing the problem. Compress your album images to about 800kb and your good. 900+ is okay but edging it may raise the chance of the problem reappearing. I do think this problem is already fixed on the newer versions of Android, and also I'm not sure if it's Android's problem or something about Motorola's software. Anyway, yeah, that was the problem. I discovered it myself, hahahahaha

Music player problems

Hello !
Just got the phone 3 days ago. Must say its amazing ! But i've got a problem. The music app doesn't display all the songs that are on the phone. I've moved the "filter" to 0 seconds, also moved my music on the internal storage and nothing. It does show a few songs but not all. The scan app finds all of them, but shows only a few.
What could be the problem ?
Cheers

Maybe you have a file .nomedia in ur music folder that skip showing the music files.
If you have it delete it.
