I Might Be Wrong is actually one of my favourite Radiohead recordings.
That being said, I've become pretty ambivalent about the band in the time between Hail to the Thief and now. I associate them with being angry, and I just don't have the rage anymore, guys. In Rainbows will get a listen from me, but the excitement, I don't have it. Neat of them to do a sneak-attack album drop though.
