We actually did this a couple years ago. I don't remember who started it, but the way we handled it was that someone volunteers to put together a cd and then asks for takers. The goal was that each taker would then send the person who made the cd a cd mix in return. It didn't quite work out that way, but it was still fun. I did a mix, and I got mixes from five other people. A lot of the new music I was exposed to I still listen to.

It was well worth it, and I'd do it again.
