Eminem released his surprise album Music To Be Murdered By on Friday featuring Ed Sheeran, Juice WRLD, and Anderson .Paak.

On the Young M.A.-assisted “Unaccommodating,” the Detroit rapper addresses his rivalry with Machine Gun Kelly. After going back and forth with a series of diss tracks in 2018, he announces that the beef is over.

“But when they ask me is the war finished with MGK? Of course it is,” raps Em. “I cleansed him of his mortal sins, I’m God and the Lord forgives, even the devil worshippers / I’m moving on.”

As Complex points out, the “devil worshippers” line may be a reference to MGK’s 2018 Eminem diss track “Rap Devil,” where he accused Em of attempting to sabotage his career.

Marshall Mathers also mentions MGK on another Music To Be Murdered By track, the Busta Rhymes-sampled “Yah Yah,” which features Royce da 5’9″, Black Thought, Q-Tip, and Denaun. “I’m a sight to see, but you can see from the ring I’m wearing / Me and this game, we got married already,” says Em. “Had the prenup ready / Fucked on her, shoulda seen her belly / She barely was three months pregnant / Bitch had it, gave me her baby, we named it Machine Gun Kelly.”

Eminem and Machine Gun Kelly’s beef dates back to 2018. After hearing MGK’s verse on Tech N9ne’s “No Reason,” Eminem took aim at the Cleveland rapper on his Kamikaze cut “Not Alike.” Shortly after, MGK returned fire on “Rap Devil,” inspired by Em’s own 2013 track “Rap God.”

On “Unaccommodating,” Eminem also makes a controversial reference to Ariana Grande and the bombing outside her 2017 concert at Manchester Arena. “I’m contemplating yelling ‘bombs away’ on the game like I’m outside of an Ariana Grande concert waiting,” he raps.

Elsewhere, he takes a stand against gun violence on “Darkness,” inspired by the 2017 mass shooting at the Route 91 Harvest music festival in Las Vegas. The video encourages fans to register to vote in order to help change gun laws.
