8 and 9 are sewn up with KoL and PH. 7 is likely AMSP and the other six can all have solid arguments made for them. Popular opinion would have the top four as In Rainbows, Kid A, OK Computer and The Bends, which I've put in alphabetical so no-one froths. Personally I'd have HTTT, above In Rainbows, but it wouldn't be my top...so the definitive list should be:
1-4. IR, KA, OKC, TB
5-6. A, HTTT
Not that I'm calling for an end to Radiohead lists, like. Surely there's scope for top 10 songs, maybe listing the songs on each album in order of merit, favourite pairs of trousers you've seen Thom wear (must have photos to back up) and best Radiohead song/cake combo, to name but a few...
