Drake is suing his record label for spreading a “false and malicious narrative” when it released and promoted Kendrick Lamar’s diss track “Not Like Us.”

Drake’s second diss track used artificial intelligence technology to include verses from Tupac and Snoop Dogg, two of Lamar’s influences. In his own verse, Drake accuses Lamar of delaying his response track because of the imminent release of Taylor Swift ‘s “The Tortured Poets Department.” (Lamar collaborated with Swift on “Bad Blood.”)

It’s just the latest achievement for the man who was the first rapper to ever be awarded the prestigious Pulitzer Prize. After the court of public opinion gave him a decisive win in his spring rap feud with Drake, a Super Bowl halftime performance days away and an upcoming tour, Lamar is on a dominant winning streak.
