Kendrick Lamar didn’t give fans long to speculate about what exactly his cryptic Instagram post from today meant, demystifying the update in the form of “The Heart Part 4,” which dropped via Apple Music and iTunes late Thursday (March 23).

But even with this new offering, he still leaves us with the question: is the Roman numeral “IV” just a reference to this single, or something bigger, like his fourth album?

He telegraphs a future move at the end of the song, rapping: “Y’all got till April the 7th to get y’all shit together.”

We’ll be waiting.
