Heard of The Cornerstone Player?
 

At a used cd store, I picked up a cd called the Cornerstone Player. It's essentially a mixtape of current music and artists that are seemingly of the independent scene. I've done a little bit of research on it and it seems to be some sort of subscription service, where every few months perhaps you get a 2cd set of new music.

Has anybody heard of this before, and does anybody know how to sign up for this? (or where to buy more?)

It seems like it would be a really cool service and seeing as how I don't listen to the radio, this would help me keep up with what's new and help figure out what's good.

Thanks.
