J. Cole apologized to Kendrick Lamar earlier this year for his diss track, "7 Minute Drill" and removed it from his album, Might Delete Later. During his Dreamville Fest set Cole addressed the crowd: "I'm so proud of that project [Might Delete Later], except for one part," he said.
"It's one part of that shit that makes me feel like it's the lamest shit I ever did in my fuckin' life. Y'all heard that bazooka that was dropped on the game two or three weeks ago. [My dudes] are like 'What you gonna do Cole?'" Cole continued to say that the world wanted to see blood, but he spiritually felt bad. "I tried to jab [Kendrick] back, but that shit don't sit right with my spirit. It disrupts my peace," he said before asking the crowd if they thought Kendrick was one of the best MC's ever.
