I understand now to remove songs from my iPad, yet there are some songs on my iPad that are on there that I KNOW I didn't put on there. It seems they have come from Apple or from some cloud source. When I got into iTunes, they don't even show up, yet on my iPad they show up and I can't swipe the song from right to left to get to the delete key. Any ideas on how to remove these dreadful songs and dreadful artists? Thanks!
