Several users have reported that several issues (slower loadings; graphical glitches, freezings or it just doesn’t play at all) when trying to play music. This is how you fix your music app:
- Plug your iDevice into iTunes
- Open iTunes and go to the music tab on your device and uncheck “Sync Music.” This will remove all music from your device. Apply changes and sync.
- After the sync finishes go back to the music tab and recheck “Sync Music.” Apply your changes and sync your music back to your iPhone/iPod.
- Now, try playing your music now from the music app. It should work.
