Amazon's DRM-free store is #2 online music seller

Only six months after opening, Amazon's MP3 service has become the second-largest online music retailer. To differentiate themselves from iTunes Music Store, they only sell DRM-free music which comes in MP3 form that you can easily share with anyone you'd like. While Apple is moving in that direction, as of yet only about a third of their catalog is DRM-free, and Amazon has more than twice the amount of DRM-free songs available.
