Found through BoingBoing but with kudos to Eirikso. Amie Street is a cross between a digital music store and social networking site. With a view to encouraging the discovery of new music, all tracks start out free and only go up in price as they become more popular. On top of that, fans are rewarded if songs they recommend become popular. The artists themselves make 70% of song sales and never lose ownership of their work. Just as the icing on the cake too, all the music is in DRM-free MP3 and can be played on any portable player. It’s what you might call a pretty fucking clever idea.
