I can't move some of my purchased songs on iTunes into my iPod music library
before the update to iOS5 I have transferred all of my purchased items (on my iPhone and iTouch) into a playlist under "store" in my iTunes library. But some of them don't show up in the other playlists like "purchased 1" / "purchased 2" and "purchased on iTouch" / "purchased on iPhone". How can I transfer the missing ones into the music playlist again? I've tried it with drag and drop but it doesn't work. It works with my iPod nano though.
