Apple debuted DRM-free versions of some of its offerings on the iTunes Music Store, all encoded at twice the normal bit rate (256 kbps, as opposed to the standard 128). I was given the option of upgrading 28 of my songs at 30 cents a pop (which I did). Probably won't make much of a difference to my listening habits right now, but who knows what advances in audio will be coming around the corner?
