I have itunes 11 on pc. I want to remove music from my ipad only, but keep them in itunes/icloud. in the previous itunes version, there was a way to pick which artists, songs and playlists i want to transfer to my devices. I read that i could manage by selecting "manually manage music and videos" however, when i go to this section, all i can do is manually manage videos. I just don't want my entire music collection on my ipad. please advise
