So I was listening to all of the hearts and they all have similar themes.
It's Kendrick speaking from his heart, no bullshit.
A lot of the lyrics on the Heart Part 4 are like a diss track and people say it's about Big Sean but I also think it's a letter to the public after Big Steppers came out.
In fact, Damn and Big Steppers have a lot of the same themes.
In XXX, Kendrick says America is a reflection of him, a mirror.

Damn was supposed to release on April 7th.
He was telling us to get our s*** together because he was going to speak some real s*** when it released
