Serious Contenders: The Darkness, "I Believe In a Thing Called Love"

It's funny how oftentimes in music a feminine manner (tight clothes, long hair, high voice) becomes intensely masculine. It remains something of a mystery how one ends up as Justin Hawkins rather than Boy George (or worse, Pete Burns from Dead or Alive) although playing good music is a good start. The glam-rock conceit of the Darkness involves pushing forward into that falsetto voice as far as it'll go at just the absolutely most intense moments of the song, to increase its power tenfold.

It takes a lot of balls, if you'll pardon the expression (or don't, as I used it deliberately) to really sell the glam rock image. Make no mistake, this is cock-rock, but it's amazingly done and not at all ashamed of what it is.
