I was thinking about this a little more and realized that ReverbNation already has a "pay-for-listens" model where artists/bands have to fork over cash to have 'a community' review tracks and give a rating on a 0-10 scale. If a song hits higher than 8, it's allowed to submit to big name outlets (CBS Radio, etc) through their platform.
