Just go to music player, songs, then scroll to your song. Press and hold down on your song and options will open up. Press delete and presto. Gone forever.
I tried this on Albums, but you can't delete whole albums in the same way, you also can't delete the song from the playing song interface.
But at least now those bad songs i deleted are off the phone - thanks.
I got it, ok what you do. Is go to ur music, then ur gonna wanna do the multiple select thing, then pick the ones you wanna delete, then at the bottom there will be a trash can, click that, now It will delete them, but it takes a while, it took mine 24hours before they were gone
