Big Sean is not holding back. On Halloween, the Detroit spitter unleashed his new song “No More Interviews,” which finds him reflecting on his headline-making life—from his girlfriend to his exes to his frenemies.

Over a whistling beat, which he co-produced with Amaire Johnson, Sean Don reveals a troubled past with his former G.O.O.D. Music brother Kid Cudi.

“I should have learned from Hov and Dame,” raps Sean. “From Stunna and Wayne / Cudi and ‘Ye / What happened to our family ways though / When I put you on that song with Nas, you had told me that you was forever grateful / And that we brothers / So it hurt to hit the internet to find out that me and you don’t fuck with each other / Over a miscommunication / That probably could be fixed with a five-minute conversation / I’m still praying for ya though / I guess I charged it to the game / How much it cost? Around TWENTY88.”

Of course, the track references Sean, Nas, and Cudi’s “First Chain” off 2013’s Hall of Fame, but it also references Sean and Jhené Aiko’s duo TWENTY88. The feud could be over Sean Don’s new relationship with Jhené, who was previously married to producer and frequent Cudi collaborator Dot Da Genius.

In 2014, Cudi threatened Aiko over the relationship on Twitter. “if u hurt him ill kill u,” he tweeted.

In August, when a fan retweeted the old threat, Cudder responded. “The funny thing is we aint sweatin these bum bitches and these corn ball ass ni**as,” he wrote in a since-deleted tweet. “We too busy makin better music.”

“No More Interviews” doesn’t just speak on Cudi. It also references Sean’s year in music and his relationship with Naya Rivera. “My ex wanna write a tell-all,” raps Sean Don. “Fucked up thing about it is she ain’t even tell all / Like how I introduced her to meditation / Positive thinking and the books she probably read in daily rotation.”

On his end, Big Sean could be ready to drop a new solo album, his first since last year’s Dark Sky Paradise. He will perform on “The Tonight Show Starring Jimmy Fallon” this evening.
