sehlat brings us a New York Times report that Sony has agreed to start selling DRM-free music from Amazon's MP3 store. This comes days after Sony revealed plans for physical MusicPass cards that would allow DRM-free access to a small portion of Sony's library. Now that all four major record labels are on board with Amazon, some are expecting Apple to make moves away from DRM as well. From the NYTimes: "Sony's partnership with Amazon.com also underscores the music industry's gathering effort to nurture an online rival to Apple, which has sold more than three billion songs through its iTunes store. Most music purchased on iTunes can be played only on Apple devices, and Apple insists on selling all single tracks for 99 cents. Amazon, which sells tracks for anywhere from 89 cents to over a dollar, offers the pricing variability the labels want."
