Johnny Cash Biopic Funniest Musical Of The Year

Golden Globes. Doesn’t really have anything to do with music (unless you’re a Brokeback Mountain Soundtrack fan), but this has me scratching my head:

Picture, Musical or Comedy:
WINNER: Walk the Line

Actress, Musical or Comedy:
WINNER: Reese Witherspoon, Walk the Line

Actor, Musical or Comedy:
WINNER: Joaquin Phoenix, Walk the Line

Great performances, great drama. But Musical or Comedy?

Anyway, I guess my main question is: when did they add a 6th desperate housewife?
