The track, Lamar’s first solo release since his 2016 outtakes LP untitled unmastered, opens with Lamar repeating “Don’t tell a lie on me/ I won’t tell the truth about you” over a swirling vocal loop courtesy of up-and-coming singer Khaled, who tweeted about his contribution.
After repeating the chorus once more, “The Heart Part 4” makes a sudden shift and Lamar increases the intensity, threatening an unnamed adversary, “My fans can’t wait for me to son ya punk ass and crush your whole lil shit/ I’ll Big Pun ya punk ass, you a scared little bitch.”
Midway through Lamar’s ferocious, seemingly endless second verse, the rapper takes aim at the new president and his administration’s Russia problem.
“Niggas is fake rich/ Bitches is fake bad/ Blacks that act white/ Whites that do the dab,” Lamar says. “Donald Trump is a chump, know how we feel, punk/ Tell ’em God comin’/ And Russia needs a replay button, y’all up to something.”
The track concludes with the lines, “You know what time it is, ante up, this is in forever/ Y’all got ’til April the 7th to get your shit together,” leading to speculation that Lamar plans on releasing new music, potentially his fourth album, in two weeks time.
“I think now, how wayward things have gone within the past few months, my focus is ultimately going back to my community and the other communities around the world where they’re doing the groundwork. To Pimp a Butterfly was addressing the problem. I’m in a space now where I’m not addressing the problem anymore,” Lamar added. “We’re in a time where we exclude one major component out of this whole thing called life: God. Nobody speaks on it because it’s almost in conflict with what’s going on in the world when you talk about politics and government and the system.”
