There was a time when Xzibit was known for more than just being the host of MTV's Pimp My Ride. He was one of the best rappers on the West Coast and had gold and platinum selling albums. He collaborated with the likes of Snoop Dogg, Nate Dogg, Warren G, and Dr. Dre. Dre even executive produced his 2000 album Restless as well as 2002's Man vs. Machine.

He also had a number of standout tracks with Eminem and the two had great chemistry. 2000's "Don't Approach Me" found the two artists dealing with their recent fame and addressing criticism from the media. "And I'm the bad guy, cause I don't answer my door like 'Hey hi/You guys want some autographs? Okay, form a straight line,'" rapped Eminem. They got back together on 2002's "My Name"—a diss aimed towards Canibus, Jermaine Dupri, and Moby where Eminem flipped Nas' flow from "Ether." They also both appeared on Eminem's "Bitch Please II" and Dr. Dre's "What's the Difference," both classic cuts.

Xzibit hasn't really been a factor in hip-hop for the past few years (though he had some great scenes in The Bad Lieutenant: Port of Call - New Orleans where he smoked crack with Nicolas Cage) and could use some life injected into his career. Who better than Eminem to help out an old pal?
