The embattled rapper produced Carti's "Backdoor" featuring the "Not Like Us" artist on I Am Music.

Music is finally here. Music took about four and a half years to materialize, and Playboi Carti matches the long wait with his longest, most wide-ranging album—a nearly 77-minute record that boasts blockbuster features and makes official several fan-favorite snippets.

Consequently, rumors fly - like the ones that say Kanye West produced a song featuring Kendrick Lamar on Playboi Carti's blockbuster new album "Music" (yes, the title is just "Music," even though the artwork reads "I Am Music").
