In 2007, Amazon announced their music store. It would, they promised, deliver DRM-free music to U.S. Amazon users. And they did just that. With much fanfare, they rolled out Amazon MP3, touting music downloads for any device. On their website, they explain what's special about their music sales. "DRM-free means that the MP3 files you purchase from Amazon.com do not contain any software that will restrict your use of the file."
