I LOVE Radiohead, and although their song is played as the credits roll, it is still one of my faves from the movie, if not my absolute favorite. Let's just say that JJ and I sat through the credits in the theater. Several times. I have no idea why it wasn't included on the soundtrack (and speculation abounds!) but I already owned the In Rainbows cd, so I was ok with that. It just requires a little more disc-switching to get my Twilight fix - one of my many daily doses - during my grind of a commute.
Enough rambling from me - enjoy this video put together by the talented Gilmorequeen!
P.S. Radiohead/Twilight image from HERE - she has jpegs for each song/artist on the soundtrack (and this isn't the best one...) - check it out!
