"Love Game" finds the two superstar rappers trading verses about ex-girlfriends over a track built out of samples from the 1965 song "Game of Love," by Wayne Fontana and the Mindbenders. Both Eminem and Lamar go in hard on women who've wronged them in the past, with Em attacking a former fianc�e for hooking up with everyone from Kanye West to Lebron James to disgraced former mayor of Detroit, Kwame Kilpatrick.

Earlier this summer, Lamar said he had yet to work with Slim Shady, despite a widely circulated photo showing the two of them in a recording studio together.

"I wish," Lamar said during a radio interview. "We haven't really gotten a chance to build in the studio like that. I basically just met him for a second. But if I get that call, I'm definitely running."
