It seems as if there is no way to add tracks or playlists to the iPod without overwriting what's already on it. This can't be right.

I know how to extract music from the iPod to put back into iTunes (thanks for the link, Mr MidFi) but having to copy the entire iTunes library just to get a couple of new songs on the iPod is a major PITA.

Am I missing something or is it designed this way to discourage people from raiding other peoples' iTunes libraries?
