wpegg: Killing in the name of was a good choice last year. I was really hoping they'd follow that up with something from The Prodigy. While it would be amusing to see that hit number one, I just don't think it would get the support. Whereas a specially re-made video of Smack my Cowel up, definitely would.
The general idea should have been to pick something I wouldn't feel ashamed to include in my collection. Even at the back out the way somewhere... Prodigy would have been a good choice.
Delixe: Spread the word. It can do better than buying it yourself.
I know people that will do this just for the hell of it. Hell, I bet Akwater would be down to buy a few... dozen.
