Very interesting post over at TechCrunch about Amie Street Music. They offer DRM-free music downloads whose price varies according to popularity. All tracks start off free, and the price rises as the track is downloaded more often (to a maximum of $0.98). Fascinating idea. As Monsieur Arrington says Market driven prices and no DRM = Music Nirvana. Shame that the first release from more mainstream labels/artist is the Barenaked Ladies, but you can’t have everything I guess.
