Transferring music from iPod nano (2nd Gen) to a newer model without using the original computer that you synced with?

Hello,

I was just wondering if there was a way of transferring music from my iPod nano (2nd gen) to a newer model?

I dont have use of the computer I orginally used to put the music onto it and I would like to preserve the songs that are on there.

Or is it possible to sync my iPod to another computer without erasing the music?

Thank you.
