Apparently Radiohead has decided to let people name their own price for downloading their latest album, and that includes naming $0 as your price.
Here is where you should insert the standard disclaimer about how if you really like their music and want to support them, you should pay for it. However, free is free. Go here and keep clicking through to the download.
(If you have no idea what I’m talking about but you have a teen with an iPod, you may be able to score yourself some cool points with this one.)
