How do I remove songs from my iPhone 5s running IOS 8.3? There is a U2 album on my iPhone which I didn't download &amp; isn't on my Mac &amp; I am unable to remove it.

I deleted all Music app storage from the phone, then re-synched with 1 playlist from iTunes on the Mac, but the album still appears on the phone under genres, artists &amp; albums but not playlists.
Yes, what you need to do is go into settings on the iPhone, then iTunes &amp; App Store, and disable Automatic Downloads of Music. 

Apple applied the U2 album to everyones account so if u have this option turned on, then it auto downloads.
