2 + 2 = 5

heres my list...you can tell OK Computer is my favorite Radiohead record

1. Paranoid Android - one of my favorite songs of all time and THE definitive Radiohead song in my view
2. Let Down - maybe not a favorite by the majority, but this song is just gorgeous. The ending completely entrances me to this day. If it weren't for Paranoid Android being as brilliant as it is, I'd have no qualms saying this is the best Radiohead song.
3. Fake Plastic Trees - a typical choice, but the buildup is just so intense, and when Thom holds that beautiful note and the last verse comes busting in with Johnny's frantic guitar in the background - how can it not give you chills?
4. Street Spirit - dark, haunting, emotional, who knew a few chords could say this much?
5. Idioteque - this was the song that cemented for me that Radiohead can do anything right. Even make me fall in love with electronic music.
6. No Surprises - probably the prettiest, most sparkly song in the band's catalog.
7. Karma Police - another obvious choice, but seriously who doesn't love this song?
8. Exit Music...For A Film - another one that's got alot to do with the buildup. Just a fantastic song, and it sounds like Thom is right in the room singing to you.
9. Pyramid Song - this song is just brilliant. Everything in the song seems to be on it's own time signature - the drums, the vocals, the piano - but it just all works.
10. The National Anthem - definitely the Radiohead song that "pumps me up" the most. It's just got such a great groove and driving rhythm to it, and from the videos I've seen Thom gets so into it that it looks like he's having a seizure when they play it live
