LowSNR writes "Amazon this morning moved their DRM-free music store into open beta. According to the release, 'Since all our digital music downloads are DRM-free, you can play them on anything that plays mp3s including PCs, Macs(tm), iPods(tm), Zunes(tm), Zens(tm), iPhones(tm), RAZRs(tm), and BlackBerrys. Plus, our Amazon MP3 Downloader application makes it easy to add your downloads to iTunes(tm) and Windows Media Player(tm), so you can sync up your devices or burn your music to CD hassle-free.' Not to mention Linux." Of course, without DRM few of the major labels play with them.
