• This Just Blaze-produced expletive-laden song, in which Eminem takes aim at various targets and eggs on haters to take him on, is the opening track from his seventh studio album Recovery. The Detroit MC told his Shade 45 satellite-radio station about the album: "I definitely feel like I'm in a little different space right now," he said. "With the last record, it had a lot to do with me getting sober and just my eyes being open again and my brain went into overdrive. With Relapse, I was just trying to prove to myself that I could do it again. It was a [reintroduction] and what made me in the first place with the zany, loony, ridiculous sh--. I felt like a lot of that album, I kind of wanted to [spit] rapid fire and [do] punch lines."
• This is one of three tracks on Recovery produced by Just Blaze. The New Jersey hip hop producer is best known for his work with Jay-Z on such tracks as "Girls, Girls, Girls" and "Show Me What You Got." He has also worked with Kanye West, Usher and Mariah Carey.
• Eminem spits on this cut, "But take a look at Mariah the next time I inspire you to write a song." Slim Shady has claimed he had a relationship with Mariah Carey in 2001 and previously alluded to it on his Relapse track, "Bagpipes From Baghdad." Ms. Carey denies the entire affair.
