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.”)

The rapper's Grammy-winning diss track about Drake is currently the subject of a defamation lawsuit against Universal Music Group.

Speculation over surprise guests is at a fever pitch. One name is already locked in: longtime collaborator SZA, which is of no surprise since the two announced they'd be going on tour together. This is Kendrick Lamar though so there will be more guests.
