No idea.
My idea is to organize a group of 4-5 people to form a "band". We can sub one of our own songs from each of our backlogs, or, we can do the amazingly COOL thing and collab on some original awesome material and take the "online band" persona to a new level.
At $100 a year for an account, it would only be $20-$25 per person, depending. That is TOTALLY doable for most people.
Edit: Also, to be fair, the offer would have to be open only to proven musicians who can meet deadlines and not just say "oh, yeah... I'll get to it".
