Sounds like a fun idea. As somebody who stopped downloading illegally a few years ago, not that I really did a lot, I think that I could still participate, if all choose something obscure or unique that others might not normally be exposed to and included only one song each for every artist. In this way, it becomes more of a promotional demo that would encourage CD/DVD sales rather than inhibit.

Of course, one could easily argue against it as well but that's how I would approach it.

With great power comes Awesome irresponsibility.
