Something popped into my head the other day, would be fun to find out what you lot can add to it ...
Musical opposites - take a tune and a performer that would sound cool/funny/wierd together.
I'd love to hear Cameo's 'Word Up' sung by Daleks, or Motorhead's 'Ace of Spades' sung by Celine Dion :-)
(yes this has replaced the annoying song game in my head ... argh!)
