When I am downloading songs to my iPod (15gb new models), it sometimes hangs on a song. Even when I bring everything down and up again and start downloading again, it hangs on the same song. But if I delete the song out of the library, it gets thru and keeps going til it hits another song it can't download and I go thru the same thing.

This happened on 4 songs out of about 5 CDs. Any clues?
