Kendrick Lamar teased fans Thursday (March 23) morning with a mysterious Instagram post and Thursday night, he dropped a brand new single "The Heart Part 4." The song is available to listen to on Apple here.

The Compton rapper dropped "The Heart Part One" on YouTube way back in 2010, and "The Heart Part 2" was on Lamar's 2010 mixtape, Overly Dedicated. "The Heart Part 3 (Will You Let It Die?)" dropped on SoundCloud just prior to 2012's good kid, m.A.A.d. city.

So that new album is coming soon.

On the Terrace Martin-produced "The Heart Part 4," K. Dot is spitting flames.

"N----s is fake rich, b----es is fake bad/Blacks that act white, Whites that do the dab/Donald Trump is a chump, know how we feel, punk/Tell 'em that God comin'/And Russia need a replay button, y'all up to somethin'/Electorial votes look like memorial votes/But America's truth ain't ignorin' the votes/It's blasphemy, how many gon' blast for me?/'I prophesied on my last song, you laughed at me/Oh when the shit get bracket, don't you ask for me..."

Lamar has shed some light on where he may be heading creatively on this album.

“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,” he told The New York Times earlier this month. “To Pimp a Butterfly was addressing the problem. I’m in a space now where I’m not addressing the problem anymore.”
