I do like a bit of Fleetwood Mac myself (the song "Hold Me" being one of my faves) but the Beatles have been much more influential. Not to mention quirkier tunes...
BTW, has it been mentioned that when you have four semi-finals it's actually the quarterfinals? Threw me off when I first saw the first two rounds: "No Beatles or Stones WTF?"
EDIT: Oops LOL still no Stones. Who'd they lose to?
