About “The Heart Part 4”

On “The Heart Part 4,” Kendrick Lamar floats across four distinct beat changes, describing his industrious lifestyle while challenging his contemporaries. He finishes the song with the line “Y’all got ‘til April the 7th to get y’all shit together,” which is when TDE released the pre-order for his new album on iTunes. The song is Kendrick’s first single of 2017, which he initially teased in a now-deleted Instagram post the day before its release.

The sounds in the background at the beginning are present on DAMN.’s seventh track, titled “PRIDE.” The first beat switch at the 1:20 minute-mark is taken from track twelve, titled “FEAR.,” while the second transition at 1:38 is from track four, titled “ELEMENT.”
