The Bends is their best as far as being consistently good all the way through, and a great listen
as an album start-to-finish.
OK Computer is close, and it had several amazing songs -- in fact, its best songs might be better than the best songs from
The Bends -- but "Fitter, Happier" and "Electioneering" both suck so badly I can't stand listening to them: so it can't be better than
The Bends, which I don't have to fast-forward through at any point.
Pablo Honey is in third place: inconsistent, but overall a very good album.
About a third of
Kid A and
Amnesiac each is good. The rest of those albums blows.
And with
Hail to the Thief and
In Rainbows and since, they've been pretty much dead to me. Apparently they took the {censored}ty parts of
Kid A and
Amnesiac and decided to evolve in that direction, perhaps owing to the same "waaaah, it sucks writing music that is popular" attitude that was apparent in that execrable
Meeting People Is Easy movie.
