^I was referring to the whole brooding/emo image, not the music itself.
Also, the fact that the coin landed on the "live" side when he fell down hinted that Two-Face may have survived.
I think that was meant to add a bit of pathos--Dent wouldn't have killed the kid, but Batman couldn't have known that.
I don't get the need for some to think Dent might have survived--that would render the end of this movie meaningless.
Batman was always the darkest, most somber, on the edge character.
"Always"? Haven't read much '50s/'60s Batman, have we...?
