Via Techcrunch, this looks interesting...Amie Street:
Amie Street, which launched in July, has a brilliant DRM-free music sales model. Bands upload music, which can then be downloaded for free by users. As songs become popular, the site starts to charge for it. They start at $0.01 and go up to $0.99. Users looking for popular new stuff go right to the more expensive songs.
Theme by Danetsoft and Danang Probo Sayekti inspired by Maksimer
