Get Nicki to make a diss record and just talk over the intro and outro.
Kendrick left Nicki's name off his list of targets on "Control." It was a little mystifying why; Nicki is surely as much a part of Drake and Kendrick's generation, even if she is a little older. But if she fired shots at Kendrick? Lyrical fireworks. Think about the chaos! Think of the thinkpieces!
The thing is, if anyone in hip-hop has the skills to battle Kendrick on a mainstream stage, it's Nicki Minaj.
