Lil Mouse explained his process in the studio, and reveals that he's been writing his own rhymes since he came on the scene at twelve years old. The Chicago rapper added that he doesn't always put his lyrics to paper when he goes in the booth, but Mouse says he likes to "write it all down." 

The young emcee also shared his definition of "Drill" music during his sit-down, and uses fellow Chicago rappers Chief Keef and Lil Durk as examples of artists properly executing the sound.
