It's kinda funny how Apple was saying all those years to indies who wanted no DRM on their tracks that it would be "difficult to implement" and "confusing to the users" to have both DRM and non-DRM tracks in the store. But when EMI asks, it's suddenly no big deal at all.
P.S. Aha, there's a catch: DRM-free tracks will be 256kbps, but sold for $1.29.
