Uncle Murda is ending the year with "Rap up 2019"—a 10-minute cut in which he looks back at some of the biggest moments of the year. And let's just say he wasted no time going in.

The track begins with Murda taking aim at singer K. Michelle, who recently raised eye brows with a tweet in support of 6ix9ine.

"Idc idc im happy 69 is getting out," she wrote on social media, referring to the rapper's light prison sentence. "That man is so entertaining and I like his music. Shit he didnt snitch on me, and if somebody tried to kill me I’m snitching 2,and im snitching on you cheating n**as. Lol. Half these rappers y’all like ARE NOT ABOUT THAT LIFE. Big FACTS."

Murda caught wind of K. Michelle's post and warned that she would appear on "2019 Rap Up."

He wasn't bluffing.

"K. Michelle can't keep her man, 'cause her pussy stink ... Why back talkin' about that girl's pussy stinkin'? 'Cause she put up a post co-signing Tekashi snitchin'," Murda rapped before taking aim at 6ix9ine. "Tekashi really told on all of his homies/His baby mom's fuckin' one of his homies ... Wish Nipsey was alive and they killed 6ix9ine/Nip was like Malcolm X and 2Pac combined."

Murda also fired shots at Tank, R. Kelly, the Gucci label, Jussie Smollett, Oprah, and Kanye West.

"Kanye promoting God 'cause his new album comin' out/But really he in for a bank roll," he rapped. "He ain't even write that 'Jesus Walks' record, ask J. Cole (Rhymefest did)."

Murda also took a jab at Lil Reese, who was hospitalized last month after being shot in the neck: "Lil Reese got shot in the neck, I’m happy he OK/He lost his voice, we ain’t wanna hear his new shit anyway."

Reese fired back on Twitter:

"Rap Up 2019," produced by Great John, is available on all major platforms, including YouTube above. Murda also references Meek Mill's legal battle, JAY-Z's NFL deal, Lil Nas X's coming out, George Zimmerman suing Trayvon Martin's family, Carmelo Anthony returning to the NBA, and the "new queen" Cardi B.

The track, naturally, received mixed reactions, with some applauding the rapper for refusing to bite his tongue, while other criticized some of the lyrics as sexist and homophobic. Check out some of the reactions below.
