Since updating to iOS 7 I can't delete a whole artist or a whole album from my iphone. You either have to delete song by song or all songs. Is this right? Seems like a backwards step.
Yes, that is correct.
I also have this issue. It makes managing what music you keep on the iPhone needlessly difficult.
It really should be possible to delete music in the same ways you can add music, i.e. by album, artist, playlist etc.
