The rapper Drake has sued Universal Music Group for defamation, alleging the music empire of promoting a diss track against him last spring.

If the Compton rapper performs 'Not Like Us' during the Super Bowl halftime show, could he be sued for defamation? We ask criminal defense attorney Ken White.

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.”)
