Kendrick Lamar returned to late-night TV tonight with a special appearance on The Tonight Show Starring Jimmy Fallon. As a surprise, Kendrick actually premiered a new song called "Untitled 2" during his performance on the show, much like he did on The Colbert Report back in 2014. This performance was just as crazy as the prior, as Kendrick completely spazzed under the dim lights of the set. Naturally, the new Kendrick song was absolutely crazy, as called TDE the mafia of the West and called himself "Cornrow Kenny" multiple times during the track. 

 Kendrick never released the "Untitled" song that he performed in 2014, and it will remain to be seen if he ever plans to drop the new song he did tonight. During the interview portion of the show, Kendrick and Fallon talked about the Mario Kart mashup with "Swimming Pools (Drank)," how Kendrick blows off steam, and much more. On his 11 Grammy nominations, Kendrick said that he's glad he didn't pass Michael Jackson's record of 12 nominations in one year. As far as the sampled songs on To Pimp a Butterfly, Kendrick said that it was all stuff that his parents played while he was growing up.
