OK Computer is a bit of a retroactive classic. When it came out after The Bends-which is a pretty amazing album and one of the best albums of the 90s period-the general reaction to it, especially to "Paranoid Android" was frankly 'what the fuck is this?"-and not in a good way. Sure, people liked it then, but a lot of "OK Computer is a CLASSIC" came from people who got into Radiohead in the past 10 or so years. The reception upon release was a flat "what?!" I loved Radiohead until OK Computer, and think they lost the plot there and it only got worse with Kid A. But that's just me.
