I'm trying to create playlists using iTunes on my computer, and transfer them to my iPod classic. But when I try to transfer them, I get an error message that says, "These songs will not be transferred because they are already on your ipod." Of course, that's true, but it's never been a problem before. I've been able to create playlists of songs that are both in my laptop iTunes library, and on my iPod, and transfer them. Now I can't. Does anyone know what I should do? Thanks very much for your help!
