move from OLD computer to NEW computer

OK, We have an older Gateway with some Zune content on it, songs.  How can I get these to move over to our new computer so that the songs that we purchased on the old computer are in my play list on the NEW computer?

do you have some sort of Flash Drive or portable memory device? 

if not, if you have the zune software on both computers, you can use the zune device to transfer the content from one machine to the other.  ask if you need any specific help =]
