No list of the greatest albums of the 1990s would be complete without Radiohead’s third studio album, OK Computer, nor would any list of the greatest albums of all time, for that matter. I could go on for hours about how freaking amazing, influential, and ahead of its time the album was but you probably already know and, if you don’t, you should learn. The album was so great, in fact, that it’s now going to be preserved in the Library of Congress.
