I know that the song "(Coffee's for Closers)", by Fallout Boy (it's on their latest album, Folie a Deux) is full of support for Obama. Here's a sample of the lyrics to show what I mean:
"I will never believe in anything again, I will never believe in anything again. Oh, change will come, oh change will come..."
Also, from the same album, in the song "20 Dollar Nose Bleed":
"When I look at the man who would be king.
The man who would be king, goes to the
desert, the same war his dad rehearsed.
Came back with flags on coffins and said
"We won, oh, we won""
Internets for anyone who understands that. It isn't hard.
