Amazon MP3 has the only digital music catalogue that offers DRM-free tunes from all four major labels, with around 3.3 million tracks in the library, they are packing some weight. If that fact doesn't have Apple quaking in their boots, the competitive pricing should. We couldn't care less how Amazon and Apple get down and dirty, but as they are bound to be set for a fight, teeth gnashing and all, it can only mean good things for customers. DRM-free music will have a bigger global presence, and that should solidify its worth in the consumer market. Also, the ensuing price war is not going to be too bad either. After all, iTunes surely cannot keep their offerings priced above the competition, whilst simultaneously offering DRM gimped and comparatively expensive ($1.29), DRM-free tracks. It's about to get interesting—watch this space. [Amazon]

Monday, in fact, is the day the service goes live, and we cannot hold our wee we're so excited. Initially, only Windows Vista and XP will be supported, but the Macboys and girls see some action on March 18th.

The system will work by tracking all downloads, royalties will then be issued accordingly. It isn't too clear how that revenue will be generated, but expect some anal advertising to bombard a PC near you if you do give it a whirl. Still, we can't help our cynical judgement chiming in—how did Noah get two of every species on a wooden boat? He didn't—do you know what I mean? Nevertheless, we wait and hope for a legal, free, P2P music service, but we think eternal world peace is a little more likely by Monday. [Boy Genius Reports]
