Rap Devil

"Rap Devil" (stylized in all caps) is a diss track written and performed by Machine Gun Kelly. It was released on September 3, 2018, by Bad Boy and Interscope Records, as a single from the rapper's second extended play, Binge. The song's title is a play on Eminem's "Rap God", and is his response to Eminem dissing him on two songs of the album Kamikaze, notably on the single "Not Alike". It peaked at number 13 on the Billboard Hot 100 singles chart in the United States.

Background and release
In 2012, Machine Gun Kelly tweeted about Eminem's daughter, Hailie Jade Mathers: "Ok, so I just saw a picture of Eminem’s daughter... and I have to say, she is hot as fuck, in the most respectful way possible cuz Em is king". Mathers was 16 at the time while MGK was 22. MGK then claimed that Eminem banned him from going to Shade 45, a radio station owned by Eminem. MGK also collaborated on a song with Tech N9ne and allegedly sent subliminal insults towards Eminem.

On August 31, 2018, Eminem released a surprise album, Kamikaze, in which he insulted several artists in multiple diss tracks, including the song "Not Alike" where he insulted MGK specifically. The specific lyrics were directed: "If you wanna come at me with a sub, Machine Gun / And I'm talkin' to you, but you already know who the f*ck you are, Kelly / I don't use sublims and sure as f*ck don't sneak-diss / But keep commenting on my daughter Hailie". This led to Machine Gun Kelly's diss track, where MGK stated over Twitter, "im standing up for not just myself, but my generation. im doing the same shit you did back in ur day. life is still real on my side, and i had to take time from the grind to defend myself from someone i called an idol. love, Rap Devil."

In an interview, Eminem had explained, "That's not why I dissed him. The reason I dissed him is actually a lot more petty than that. The reason that I dissed him is because he got on — first what he said 'I'm the greatest rapper alive since my favorite rapper banned me from Shade 45' or whatever he said, right? Like I'm trying to hinder his career. I don't give a f*ck about your career. You think I actually f*cking think about you? You know how many f*cking rappers are better than you? You're not even in the f*cking conversation." He released the response diss track, "Killshot", on September 14, 2018.
