Amplive, the author of the remix, almost gave up on his project, Radiohead: Rainydayz Remixes, when last November a couple tracks were leaked and hit the blogosphere, which eventually influenced a New York Times article.* This ended in a nasty little cease and desist letter from Radiohead, but in the end, the two made a compromise.
It's here now, it's pro bono, and I love/heart it!
Check out Amplive's site, and watch this nice little YouTube video about the project.
