The announcement comes less than two weeks after Amazon.com launched its own DRM-free (digital rights management) digital music store. Maura Corbett, a spokesperson for the Digital Freedom Campaign, said: "The industry standard has shifted in the past six months and the tide has turned in favor of consumers. The number of digital music retailers offering DRM-free music will soon outnumber those that do not, and consumers will soon live in a world where they can listen to legally purchased music when, how, and where they want. We congratulate Microsoft for joining the growing number of retailers and labels that have realized the best way to increase the sales of digital music, is to listen to their customers."
