Good point. I don't want to put rules or restrictions on this contest so I'm going to say do what you want. I think it'd be a hoot for all of us to hear anything creative our collegues have to offer, including re-record, add parts etc. That said, if you just want to re-mix using the existing source material, that's fine too. Heck, cut it up and make it a dance mix if that's what grabs you!
