One might say Kendrick Lamar’s “6:16 in LA” is “Taylor Made.” A rep for Jack Antonoff confirmed to Billboard that the Bleachers frontman and frequent Taylor Swift collaborator worked on K. Dot’s latest Drake diss track.

Antonoff co-produced the seething “6:16 in LA” alongside Lamar’s in-house beat maestro Sounwave. (Variety was first to report that Antonoff co-produced the track.) The rapper uploaded the Al Green-sampling diss taking aim at the 6 God to his Instagram account on Friday morning (May 3).

In the track, Kendrick continued his psycho-analyzation of Drake while accusing OVO of having leaks in its camp. “Have you ever thought that OVO was working for me?/ Fake bully, I hate bullies/ You must be a terrible person/ Everyone inside your team is whispering that you deserve it/ Can’t Toosie Slide up out of this one, it’s just gon’ resurface,” he raps.

Lamar continued to hammer home allegations of betrayal behind Drake’s back while spewing: “100 n—as that you got on salary/ and 20 of them want you as a casualty/ and one of them is actually/ is next to you / and two of them is practically tied to your lifestyle.”

Kendrick shared the track on social media with the cover art featuring a black Maybach glove. Fans began to speculate the meaning behind “6:16,” and some brought upon theories of June 16 being 2Pac’s birthday. Drake used AI-assisted Pac vocals in his “Taylor Made” freestyle, which he deleted from social media following a cease-and-desist from the late rapper’s estate.

Others pointed to June 16 being Father’s Day in Canada this year, while producer 9th Wonder reminded fans via X that HBO’s Euphoria debuted on that day in 2019. Drake served as an executive producer on the show, which also doubled as the title of Kendrick’s first diss targeting Drizzy earlier this week.

“6:16 in LA” arrives three days after K. Dot dropped his scathing “Euphoria” diss, and the 6 God is yet to officially respond.

However, Drake appeared to react to “Euphoria” by posting a clip from the 1999 rom-com 10 Things I Hate About You on Instagram, and hinted at his retort while leaving the stage after a surprise appearance at Nicki Minaj’s Toronto stop on the Pink Friday 2 World Tour on April 30. “You know what time it is — you know what I have to do,” he cryptically said at the time.

Antonoff’s work on “6:16” comes as a surprise, and serves as his first collaboration with Kendrick Lamar. Earlier this month, he helmed Taylor Swift’s The Tortured Poets Department as the primary producer; the record-breaking album arrived on April 19.
