Help, my ipod already has songs from 5 computers?

My video ipod already has songs from five computers. I recently bought a brand new mac and starting buying songs from itunes. Itunes wont allow me to play these songs since i already have five. Is there anyway to get around this? Can i somehow figure out which songs came from one of the computers and delete those?

Thanks in advance!

Interesting.. I never heard of this..

This is what I would try.. Take all the songs off your ipod and put them on a friends computer.. and then put your new songs on your ipod.. then go to your friends and see what you can put back on your ipod. I hope this helps.
