Eminem Jumps on Kxng Crooked's 'Welcome to Planet X': Listen

No use in lying: Eminem's been right at the front of our brains since he showed up out of the blue with the brain-bruising "Campaign Speech." And fortunately he isn't retreating back into the Detroit depths for an extra-long time, already re-emerging to narrate the intro of Slaughterhouse member Kxng Crooked's new song "Welcome to Planet X."

"I live in a world...that's different than your world," Eminem says on the track, set for Nov. 11's Good vs. Evil album. "Your world still believes in things like free speech and democracy. Those things don't exist in my world anymore. Welcome to my world; welcome to Planet X, motherfucker."
