Kendrick Lamar has spent a year hammering Drake with diss tracks, one of them winning five Grammys. Will he perform "Not Like Us" at the Super Bowl?

Drake followed with another Lamar diss in “Taylor Made Freestyle,” which asserted the rapper bowed down to Taylor Swift and included an AI Tupac voice. Lamar responded with the venomous “Euphoria.” From there, Lamar released “6:16 in LA,” Drake released “Family Matters,” and Lamar dropped a sinister track called “Meet the Grahams.”
