I get worried when I see this described as "profitable". There is no way that you can describe "I spent $20 and made $6" as profitable in an honest fashion. Trying to do so just makes it sound less like "innovative method at getting new artists some exposure" and more like "pyramid scheme".
I saw these guys present to the MIT e-club.<p>Choice of the word profitable: it's profit sharing (for some percentage). There is a definite incentivization. When one uses a credit card with "cash back" or to get airline miles there's not a huge difference.<p>A novel idea - think it just needs some simplification. Maybe it'd also be good to focus on a niche, or user generated content.
This site sounds pretty interesting, but every other "buy DRM-free music" site I've seen has crippling geographic restrictions (crippling to me at least, I'm in Australia). I can't find statements one way or the other on the site - does anybody know what the deal is?
