You can't. You have to download a program called sharepod to do it. Regardless, as soon you sync your ipod to your own computer through itunes it will delete everything currently on your ipod and then you would have to re download everything back on it. Apple says you should only sync your ipod with one computer at any given time, and it syncs the way it does to hinder people sharing music. So download sharepod, use it to get the music off of the ipod. Load up itunes, add all that music you just put on your comp to your library, then resync it lol.
You could also turn off automatic syncing...
