Radiohead, "In Rainbows"

I'm listening to it right now... very cool.

You can go to their site and download it for however much you choose to pay. I paid $8, but since the audio isn't CD quality, I suggest you pay half that.

(Meanwhile, I'm not linking their site because it's currently down. I pre-ordered mine so I got it via email.)

They will be releasing an actual CD sometime in 2008.
