Watch your back

I'm coming through, don't test my crew I'll leave you feeling blue, with my lyrical voodoo I'm the king of the game, you just a pawn I'll leave you feeling ashamed, when I drop this bomb You talking smack, you better watch your back I'll hit you hard, leave you flat on your back I'm the realest in the game, you just a fake I'll leave you feeling the shame, when I raise the stakes You ain't nothing but a clown, running your mouth I'll take you down, show you what I'm about I'm the one they call the greatest, you just a hater I'll leave you feeling frustrated, when I drop this data I'm the one they call the king, you just a peasant I'll leave you feeling the sting, when I teach you a lesson I'm the one they call the best, you just a joke I'll leave you feeling stressed, when I go for broke
