First time this has ever happened to me, and I've been using the built in Music app for some time. I bought some music from Amazon. Attached my Rezound and copied it over (directory and all) to my SD card. Load up Play Music and the album isn't there at all - not a single song. If I open the build in Music app, it's there. If I go through my file manager and click on a song it plays in any app I want it to play in (Music or Play). I've restarted my phone and it still isn't showing up in Play Music
Not sure that's the issue. I've rebooted my phone, which mounts/unmounts the card, and that didn't solve it. Also, the album does show up in other music apps. The only app it fails to show up in is Play Music.
I have the same problem when I add music and go to the Google player there is nothing or only the music I last added, I have rebooted the phone and no joy, I have found though if I uninstall the last update and reinstall it all my music is back... there seems to be no help from Google and the problem persists
I think the latest version of Google Play Music has its bug. What I did is I Uninstalled the Google Play Music in Play Store, so basically it will go to its outdated version. But when I use it, It works fine now. I can play my musics fine and all.
