Harlem rapper Sheck Wes‘ breakout hit “Mo Bamba” didn’t arrive with a bang. In fact, its lyrics weren’t even transcribed on Genius until nearly two months after its release. Now, the song is racking up tens of millions of streams and steadily climbing the Billboard Hot 100, reaching a new high of No. 31 on this week’s chart. Although it’s been buzzing since early 2018, “Mo Bamba” feels like it’s just getting started.
