Just went from Windows to mac and want to bring my windows itunes playlists. when I hit export and save it on a usb and hit import in mac itunes, then I get the playlist but its all empty. It kinda sucks if I have to sort out all the good stuff again, so I hope I can get my old playlist back. I have it on my ipod touch as well, so I dunno if you can transfer playlist from ipod to mac
