MY VAGINA HURTS
In Rainbows is the work of a band who is comfortable, and just wants to record. Nobody puts a note out of place on that album, whereas
OK Computer has the steaming pile of shit that is 'Fitter, Happier.' It's restrained, and it's relaxed. Sure, it's easier to listen to - and I like that. It's a warm album, by Radiohead standards at least.
OKC is the better album, yes, as far as how it hangs together as a piece, the unification of the album as a whole; but as far as simple song-by-song strength, consistence, I'd say
IR edges it out.
