Yep, you can. If and when you get your pc up and running if you're going to reuse iTunes (if that's what you were using) just be mindful if you plug in your iPod, it will ask you to use (your name) playlist if you hit yes it will erase what you have. I think there is also a way to get all the songs off your iPod into your own playlist.
Oh, for us Apple folk, G4 and G5 are the new/er computers until I realized you ment generation LOL.
