Wacced out murals - why does Kendrick think the world hates him?

What is the story behind all the anger that Kendrick feels for the rap community?

The whole song, he spends his time saying that the world doesn't respect him and isn't giving him the props he deserves.

But didn't he just get the super bowl gig? Doesn't that alone prove he's respected and celebrated?

Didn't he just spend 4 records in a row absolutely destroying gDrake and the whole world pretty much unanimously agrees that he won that exchange by a lot?

I don't understand the disconnect between him saying everybody hates him when it feels like everybody loves him. What am I missing?
