I downloaded some app from a strange-named company Nellymoser to hook up my Ipod to the 360 so I can listen to better music while I play games. The only complaint I have is that it has to re-index my library every time I hook it up, so it can take 10-15 seconds before my playlists appear.

Given the choice, I would like a hack that lets me share my iTunes playlists straight from my computer (PC or Mac).
