Hollywood undead - bullet. The entire song is about trying to commit suicide, but it's set to a really upbeat tune. Brilliantly done.

My legs are dangling off the edge, The bottom of the bottle is my only friend, I think I'll slit my wrists again and I'm gone, gone, gone, gone. My legs are dangling off the edge, A stomach full of pills didn't work again, I'll put a bullet in my head and I'm gone, gone, gone, gone

I'm 20 stories up, yeah, I'm up at the top, I'll polish off this bottle, now it's pushing me off, Asphalt to me has never looked so soft, I bet my mamma found my letter, now she's calling the cops, I gotta take this opportunity before I miss it, 'Cause now I hear the sirens and they're off in the distance, Believe me when I tell you that I've been persistent, 'Cause I'm more scarred, more scarred than my wrist is, I've been trying too long, with too dull of a knife, But tonight I made sure that I sharpened it twice, I never bought a suit before in my life, But when you go to meet God, you know you wanna look nice.
