This has probably been asked a million times....

But this is my first time to the iPod threads so I'll ask again!

Ok, so I'm getting a used 3rd gen iPod from someone and its pre-loaded with songs. I'm gonna sift through them and see if theres anything good and possibly keep them, but I've heard that it will only sync with one computer at a time. Is there an app or method to download the tunes from the iPod onto the PC/Mac? (got both, no biggie)
