Free stuff is good. Potentially free stuff is also good.
Radiohead are releasing their new album in the next few weeks, and should you wish to you can pre-order a copy of it. However, in their label-less state, they've chosen to let you download their new album now. The interesting part is when you get to the "View Basket" page, and you get confronted with the message that you choose the price. That's right - you can pay as much or as little as you want. Personally, I gave them a bit of money purely because OK Computer is pure awesomeness, but even so, if you're not super keen, download it for free and see what you think?
