I just read about this new independent online music store, AmieStreet.com. Other than the fact that it is DRM free, the reason it is noteworthy is because Amie Street exhibits just the kind of innovation that will explode in a world without DRM. At Amie Street, songs change price (from free to 98 cents) based on how many times they have been downloaded. Artists get 70% of the revenues from their work after a flat fee for hosting and bandwidth.

As you would expect, you'll only find music from independent record labels, but Amie Street, like eMusic, is proving that there is more than one business model for digital music downloads, and that e-retailers can make a go of selling digital downloads with DRM.
