If anyone knows who sings the lyrics to this song or what song it is please let me know. Go and kick off baby. Just slip away. ah , ah, It's now your time lady, time to change the game. Though you did what you said you did. Mercy. What you'll find you need is Mercy And that one time it's mercy that saves, You gotta hurt me. You ain't worthy of this pain. Of this pain... I got it off the movie called Mafia's closing credits.
