The Beatles changed the dynamic from one handsome poster boy managed by a mildly homosexual manager to a group of handsome young poster boys with a mildly homosexual manager. But they wrote their own material, and took it to the top of the charts many times over. Before their visit in '64, no British act had made a major dent in the American media, they opened up the American market to British records. Keep that in mind before you start slagging them off, you might have never heard of NO without the Beatles first.
Having said that, I do think it's pussy-footing to keep naming Sgt. Pepper as the greatest album ever (At least VH1 spiced it up by naming Revolver instead). It's a cop-out that denys the importance of other artists. I got into Rock because of the Beatles, but that doesn't mean I believe they're the beginning and end of it all. I would argue that the Sex Pistols had as equal an impact, if not more. The Beatles are great, they are the most important band of all time, but they put out some crap as well, they were human beings with problems and egos and all that things that make us human. That got lost somewhere in the mythification of John, Paul, George and Ringo.
Now then, raise your hand if you think ELVIS pRESLEY is overrated
