Just discovered this website.

This is from the about section:

“How do we do this? It starts with the fact that all songs on Amie Street are priced from free to 98 cents. Instead of the arbitrary $0.99 per song, on Amie Street the community determines the price of music. Every song starts free, or very cheap, and increases in price, up to 98 cents, as more and more people purchase it.

This variable pricing system ensures that the public gets music at a fair, community-driven price point, and makes it easy for you to find the type of music you want. We then encourage you to talk about the music you like by putting money in your account for more downloads when you recommend songs that continue to rise in price. You can play the music you purchase from anywhere on the web and all Amie Street downloads are iPod compatible DRM-free mp3s. Enjoy the music!”

It’s a good model with the chance to find cheap music. You can discover great stuff by uploading your itunes xml file or by logging in with your Last.fm profile, as it recommends music for you based on your taste. There’s a lot of free stuff to dig up too.

This is Disappears with a tune called Lux.
