I am getting super frustrated here - I can't delete the music I put on my iphone.
I unchecked the "sync music" in itunes, press apply, nothing happens!!!
In the bar at the bottom of the screen where it tells you the space availability, it will delete everything (so it seems), but then two seconds later pops back up to my full music amount. I have it set to manually manage music, with no luck.
Please help, I want it off as it's taking too much room up!
I don't know if your still having a problem but you can delete all the songs if u go Settings -> General -> Usage -> click on music -> and swipe to delete on your phone.
