As “Whatchu Kno About Me” leads both lists, GloRilla earns her first No. 1 at the rhythmic format.

Just in time for the last chart cycle of 2024, GloRilla adds to her already strong results this year with a first No. 1 on Billboard’s Rhythmic Airplay chart thanks to “Whatchu Kno About Me,” her collaboration with Sexyy Red. The pair’s co-billed single rises from No. 3 to rule the chart dated Dec. 28. As GloRilla achieves her first leader, Sexyy Red banks her second No. 1 on the radio ranking, but first in a lead or co-lead capacity.

“Whatchu Kno About Me” advances to the Rhythmic Airplay summit after a 10% boost in plays that made it the most-played song on the U.S. monitored rhythmic radio panel in the tracking week ending Dec. 19, according to Luminate. The collaboration unseats Future’s “Too Fast,” which slides to No. 2 after one week in charge.

The new champ also borrows from a previous Rhythmic Airplay hit. It samples Lil Boosie’s “Wipe Me Down,” featuring Foxx and Webbie, which reached No. 23 in 2007 and spent 16 weeks on the list.

As mentioned, GloRilla achieves her first No. 1 on Rhythmic Airplay. Before the coronation, her previous two singles both put her in touching distance of the top spot. A collaboration with Megan Thee Stallion and Cardi B, “Wanna Be,” peaked at No. 3 in August, while the Memphis rapper’s solo single “TGIF” peaked in the runner-up spot last month.

For Sexyy Red, “Whatchu Kno About Me” secures the rapper a second Rhythmic Airplay No. 1, after she and SZA featured on Drake’s “Rich Baby Daddy,” a two-week leader in December 2023. The reigning champ is the rapper’s first time in charge through a lead or co-lead billing; her prior best in that category was with her “Get It Sexyyy” single, which peaked at No. 8 in July.

Adding to the triumphs, “Whatchu Kno About Me” rules Rap Airplay following an identical 3-1 climb. It jumps into the top slot after a 10% surge in audience in the tracking week, and likewise replaces Future’s “Too Fast,” which backtracks to No. 2 (down 11% in audience). There, GloRilla nabs her third No. 1, after “Tomorrow 2,” with Cardi B ruled for six weeks in 2022-23 and “TGIF” reigned for eight weeks earlier this year. Sexyy Red, meanwhile, picks up her second Rap Airplay No. 1, after a four-week run for “Rich Baby Daddy” in December 2023.

In addition to their current radio hit, GloRilla and Sexyy Red are together on another budding hit. The pair, alongside Lil Wayne, features on Tyler, The Creator’s “Sticky,” which pushes 10-8 on Rhythmic Airplay (up 17% in plays) and holds at its No. 11 high on Rap Airplay (up 11% in audience).
