Going to have to go with The Stones since I'm a Beast of Burden and I've always had Sympathy for the Devil. :-P

Maybe it's a generational thing, and I'm probably about to start a Rock and Roll holy war by saying this, but I always found the Beatles to be overrated. Of course, I feel the same way about Metallica, and that is my generation. I just never understood why either is considered some sort of outstanding example of their genre. To the Beatles credit, I put on their song Taxman pretty much every year I first sit down to do my taxes. :-)
