Rapper Kendrick Lamar debuted "Untitled 2" on "The Tonight Show" on Thursday.

This is the second unreleased song Lamar, who released the highly acclaimed album "To Pimp a Butterfly" last year, has performed on TV. He played an untitled song on "The Colbert Report" in 2015.

Lamar chatted with Fallon about Michael Jackson and Mario Kart, as well as all of his many nominations and honors. Fallon called him "the biggest name in music" during their interview.

Perhaps not to be outdone, Kanye West released a new track that featured Lamar as well, called "No More Parties." The song is available on his website.
