Already working to compete with Apple on the downloadable movie front, Amazon.com is looking to take on the digital music giant with a new service that will sell DRM-free.  The new store is supposed to launch this May, and Amazon has spent a considerable amount of time in the past few weeks talking to music labels in an attempt to get them on-board with the new service.  This however isn't a new initiative for the online retailer, as they've been working diligently for the last 18 months to get some sort of music service off the ground.  This latest push is just particularly aggressive.

If the service does launch on time, current guess is that it will carry music from EMI, the label already on-board with the DRM free initiative on iTunes, various independent labels, and there's even a rumor that Vivendi Universal may be interested (though opinion is that it is unlikely).

Will anyone be able to take a chunk out of Apple's massive marketshare?
