How to get rid of deleted music on my iPhone that still shows up?

I deleted a lot of music on iTunes and my Phone as my music taste has changed. Its deleted on iTunes and doesn't show up on my computer, but they'll still be on my phone. Sometimes they'll automatically play or they'll have that you cloud symbol thingy meaning to download it. I don't want the deleted music on my iPhone period! Anyway how to do this?

The music is probably still stored up in your iCloud backup. You need to erase the current iCloud backup and make a new one now that your music has changed. Go into iCloud settings to modify. Best luck.
