Pure and simple, the Trent Reznor of hip-hop.
Can go from gritty gangsta to poppy party tracks to vitriolic tirades against the American government and sound absolutely genuine while doing it.
The best lyricist in hip-hop at the moment.

-You rep me respectfully, that's how I rep for you
-Vote for who now? You're red, white and blue? I'm American too, but I ain't with the president's crew!
-Many tried, many died, come at Nas if you want a war, get it bloody....I got mine, I hope you got yourself a gun.
-I'm the leader, thats it, nobody higher Nobody touchin my crown, nobody dyin Nobody smoother, harder, tougher, believe it I'm much smarter, much more strategic.
