Marshall Bruce Mathers III (born October 17, 1972), known professionally as Eminem (often stylized as EMIN3M), is an American rapper, songwriter, record producer, record executive, and actor. Eminem is the best-selling artist of the 2000s in the United States. Throughout his career, he has had 10 number-one albums on the Billboard 200 and five number-one singles on the Billboard Hot 100. With 47.4 million albums sold in the US and 220 million records globally, he is among the world's best-selling artists of all time.

Eminem appeared on his Shade 45 Sirius channel in September 2008, saying: "Right now I'm kinda just concentrating on my own stuff, for right now and just banging out tracks and producing a lot of stuff. You know, the more I keep producing the better it seems like I get 'cause I just start knowing stuff." Interscope confirmed that a new album would be released in spring 2009. In December 2008, Eminem provided more details about the album, entitled Relapse: "Me and Dre are back in the lab like the old days, man. Dre will end up producing the majority of the tracks on 'Relapse'. We are up to our old mischievous ways ... let's just leave it at that."  According to a March 5, 2009 press release, Eminem would release two new albums that year. Relapse, the first, was released on May 19; its first single and music video, "We Made You", had been released on April 7. Although Relapse did not sell as well as Eminem's previous albums and received mixed reviews, it was a commercial success and re-established his presence in the hip-hop world. It sold more than five million copies worldwide. During the 2009 MTV Movie Awards, Sacha Baron Cohen descended on the audience in an angel costume. He landed buttocks-first on Eminem, who stormed out of the ceremony; three days later, Eminem said that the stunt had been staged. On October 30 he headlined at the Voodoo Experience in New Orleans, his first full performance of the year. Eminem's act included several songs from Relapse, many of his older hits and an appearance by D12. On November 19, he announced on his website that Relapse: Refill would be released on December 21. The album was a re-release of Relapse with seven bonus tracks, including "Forever" and "Taking My Ball". Eminem described the CD:  I want to deliver more material for the fans this year like I originally planned ... Hopefully these tracks on The Refill will tide the fans over until we put out Relapse 2 next year ... I got back in with Dre and then a few more producers, including Just Blaze, and went in a completely different direction which made me start from scratch. The new tracks started to sound very different than the tracks I originally intended to be on Relapse 2, but I still want the other stuff to be heard.
