In the minute and a half long clip, Kendrick teams up with Dr. Dre in a dimly lit studio to lay down a verse. With a blazing horn, Kendrick starts channeling Eminem, spitting a line that shouts out Pyrex and references trap rap and dope.
Dre of course looks on proudly. But, before he gets too far into the song, Kendrick calls for a time out. He's not into it. After a push from Dre to step away, Kendrick decides to go home and sleep on it. But by the next morning he's in the barbershop, Beats Pill LX speakers in hand, to play the new song for his friends. Once again we get that blazing horn, and that same line. But now we get to see Dre figure out why it is Kendrick's just not feeling it: "the drums."
