Techcrunch » Blog Archive » Amie Street Takes Innovative Music Model Into Beta:

DRM-free music marketplace Amie Street is announcing its beta launch this morning. (Note: it looks like it’s having traffic issues today, but it is coming up if you’re patient.) We wrote about the company’s alpha launch and interesting demand-driven pricing model here in July. Songs uploaded by artists fluctuate in price according to demand over time. Users get recommendation tokens for each dollar they put into the system and get free credits if the songs they recommend rise in price. Artists receive 70% of sales proceeds. The company is angel funded, with one of the most notable angels being Robin Richards of MP3.com fame.
