Grenade -- Bruno Mars

Easy come, easy go, that's just how you live take it all, but you never give Should've known you was trouble from the first kiss
Had your eyes wide open Why were they open?

(**)  Gave you all I had and you tossed it in the trash You tossed it in the trash, you did To give me all your love is all I ever asked
cause what you don't understand
Is I'd catch a grenade for ya Throw my hand on a blade for ya 
I'd jump in front of a train for ya You know I'd do anything for ya 
I would go through all this pain Take a bullet straight through my brain Yes I would die for ya baby, but you won't do the same..

Black, black, black and blue beat me till I'm numb
Tell the devil I said hey when you get back to where you're from
Mad woman, bad woman that's just what you are, yeah
You smile in my face then rip the brakes out my car

(**) 

If my body was on fire you'd watch me burn down in flames
You said you loved me you're a liar Cause you never ever ever did baby But darlin' I'd still catch a grenade for ya
Throw my hand on a blade for ya I'd jump in front of a train for ya
You know I'd do anything for ya Oh-oh I would go through all this pain, Take a bullet straight through my brain
Yes I would die for ya baby, but you won't do the same..
No you won't do the same You wouldn't do the same Ooh
You'd never do the same No no no no-oh.      (sing365)
