In a business where, for the last decade or so, every move made by a major record label or established artist is almost guaranteed to be a dumb one, it's hard to pick a mere five as the créme de la créme of stupidity.
Would the Sixties be the sixties without the Beatles? Would teen culture as we know it exist without Elvis? And can any record, no matter how brilliant, have a similar impact today? Somehow, I don't think so.
