Forget the Olympics, it's Radiohead's Greatest Hits that you need to boycott!
For background, you can read this article. In a nutshell, Radiohead's former record label, EMI, has determined what Radiohead's greatest hits are and packaged them up without any input from the band. Of course, no In Rainbows songs are included. Never mind that they have thrown "2 + 2 = 5" on the standard disk and "True Love Waits" on the Special Edition Only version. How dare they!
Radiohead -- True Love Waits
From the I Might Be Wrong: Live Recordings album.
