In Black Panther, there is a scene where T’Challa, Nakia, and Okoye enter a hidden casino in South Korea. As they enter, the song “Pray for Me” by Kendrick Lamar and The Weekend is playing. Unlike most songs in movies, this song is actually playing in the the context of the scene. The characters can hear this song. Therefore, we can conclude that Kendrick Lamar and The Weekend exist in the MCU. However, this is where we run into trouble. “Pray for Me” was released on February 2, 2018 as apart of Black Panther: The Album by Kendrick Lamar. This album was created specifically for the movie, and many songs were inspired by the film. This creates a paradox, as Kendrick Lamar clearly exists in the MCU and wrote the song “Pray for Me”. However, he would have never wrote this song or the rest of the album, had it not been for the movie Black Panther. So we can conclude, that in the MCU the real Black Panther exists, and the film Black Panther exists. Or we can also accept a different conclusion: that Kendrick Lamar and his album somehow exist out of time. Which brings me to my final and most shocking conclusion:

Kendrick Lamar is the Soul Stone
