Both rappers signed to Columbia Records last year.
Up-and-coming rappers Polo G and Lil Tjay each score their first entry on the Billboard Hot 100 chart (dated April 6), as their single "Pop Out" debuts at No. 95.
The track, on which Lil Tjay is featured and which was released in January, drew 9.4 million U.S. streams (up 38 percent) and sold 1,000 downloads (up 91 percent) in the latest tracking week, according to Nielsen Music.
Polo G, 20, who has also rapped under the monikers Capalot, Polo Capalot and Mr.DoTooMuch, is from Chicago's North Side and signed to Columbia Records in October. "Pop Out" is his first entry on any Billboard chart. He drew buzz last summer with his song "Finer Things," which he wrote while incarcerated in Cook County Department of Corrections in Chicago.
