In January, rising Chicago rapper Polo G linked up with the Bronx’s Lil Tjay for their first collaboration, “Pop Out.” The track landed each of the young rappers their first hit on the Billboard Hot 100 chart, where it has climbed into the Top 40. “Pop Out” was a viral hit from the start because of Polo G and Lil Tjay’s previous buzz, but interest grew after the duo performed the song on Genius' Open Mic series in late March. An audio clip from the performance was uploaded to TikTok, increasing the number of videos made with the track on the app.
