Radiohead are like gods in my mind, they will not disappoint. And if they do initially, listen to them again. At first I didn't mind Radiohead, but I wasn't a huge fan of them. Then I bought In Rainbows a few years ago and fell in love <3
I actually have 156 Radiohead songs on my iPod right now...
EDIT: 166!
Well, someone told me that
2112 by Rush is one of the best musical works ever, and while I thought it was good, I was somewhat disappointed. And this is someone who shares a lot of the same tastes as me. So I take what anyone else says with a pinch of salt, my tastes are my own

Turns out Radiohead are massive fans of
Live at Pompeii which I'm actually watching right now.
