Any theme with a downloadable full version works for me, but if I should pick one, I'd say the credits song of GOD HAND. It sounds like a over excited tokusatsu theme song from the seventies, and was blatantly made for laughs, but it still a kickass song.
"Dragon kicking you ass into the MILKWAY (Milkway!)! Don't act like you don't like my BALL BUSTER (Ball Buster!)! My arm, my arm, my arm, my arm, the sum of the powers of the GOD HAAAND!"
Oh, I just love this song...
