With a tumbling flow entirely unlike his contemporaries, rapper M1llionz skated across the U.K. drill beats of the late 2010s and early 2020s, putting on for his Birmingham home as one of England’s fiercest new talents. After breaking into the U.K. rap industry with the traditionalist drill of 2019’s “North West,” the rapper immediately caught eyes with his singular flow, a seemingly effortless vocal style that trickled out his bars in unconventional patterns. Quickly touted as one of the genre’s most promising new MCs, Cunningham found his breakout moment with the inventive single "B1llionz": with a vocal-chop beat from Bkay and infectious refrain (“Everyone cattin' man's style, Every day a new you with a M1llionz flow”), the track’s relentless verses landed it tens of millions of streams online, went to number 39 on the U.K. charts.
