"...This is Delirium, let's hit overdrive!
This is Delirium, Apocalypse in style!
Amps up to eleven, Ruler of these streets!
Stay surfing above waves of monsters and freaks
THIS IS DELIRIUM!..."

I love this song. Granted it's for a game, but basically I feel this is a new spin on what the apocalypse could be like.
Where it's often seen as dark scary or even sad, this plays it as the best moments. And to be honest, when your world is going to end, why not go out in style?
