Eminem has dropped a surprise album release yet again - this time a Deluxe Version of his January 2020 album Music To Be Murdered By.

Music To Be Murdered By - Side B features 16 brand new tracks on the project, with his new music video for 'Gnat' dropping today.

The music industry and fans alike began to suspect that Eminem would release the record’s deluxe edition this week, after an unverified press release was leaked online earlier this week.

“Uncle Alfred Hitchcock heard you screaming for more...enjoy Side B,” Eminem said upon the work's release.

Eminem plays multiple characters in the clip, including a patient still banged up after a stint in the hospital and an essential worker in a hazmat suit.

“These bars are like COVID / You get ’em right off the bat,” he raps.

He also mentions giving Billie Eilish nightmares after the 18-year-old Grammy winner said that she was scared of him her entire life.

"Terrified," she said in a 2019 interview. "That dude freaked me out, oh my God."

In response, Eminem raps: "But really I’m just fulfilling my wish of killing rhymes / Which is really childish and silly, but I’m really like this / I’m giving nightmares to Billie Eilish.”

He also issues an apology to Rihanna for his previous lyrics about Chris Brown.

One of the new tracks, ‘Zeus’, sees Eminem holding himself accountable for a decade-old song that was leaked last year on which he rapped that he “sided with Chris Brown” over Rihanna after Brown pleaded guilty to felony assault in 2009.

“But, me, long as I re-promise to be honest / And wholeheartedly, apologies, Rihanna,” he raps. “For that song that leaked, I’m sorry, Ri / It wasn’t meant to cause you grief.

“Regardless, it was wrong of me.”
