so i want to manage my music, but im never at my computer where all the original songs are stored on itunes. I want to delete songs/artist on my iphone when im using it. I know this can be done by swiping. But the problem is that my iphone is synced with itunes, and at the end of the day when i come home, the songs are re-downloaded back into my iphone. Nor do i want to go into itunes and manually delete the songs i deleted on my iphone. pls help.
