GloRilla links back-to-back No. 1s on Billboard’s R&B/Hip-Hop Airplay chart as her collaboration with Sexyy Red, “Whatchu Kno About Me,” replaces her own “TGIF” at the summit. The switch happens on the list dated Jan. 25, as “Whatchu Kno About Me,” released on CMG/Interscope/ICLG, jumps from No. 3 to become GloRilla’s third champ and Sexyy Red’s first leader on the radio ranking.

“Whatchu Kno About Me” reaches No. 1 on R&B/Hip-Hop Airplay, which ranks songs by combined audience totals across monitored adult R&B and mainstream R&B/hip-hop stations, with 16.3 million audience impressions in the U.S. in the tracking week of Jan. 10-16, according to Luminate, a 16% surge from the previous week.

The new champ evicts GloRilla’s own “TGIF” from the penthouse after the latter’s 16-week domination from October to January. The move is actually the second straight self-replacement atop R&B/Hip-Hop Airplay. Directly before “TGIF” captured the throne, Kendrick Lamar successfully engineered a self-swap: The rapper’s “Like That” collaboration with Future and Metro Boomin ruled for three weeks in June before ceding the top slot to “Not Like Us,” which wrapped 15 weeks at the summit.

Among women, GloRilla’s self-replacement is the first since Tems accomplished it in November 2022. Then, the singer-songwriter and Drake featured on Future’s “Wait for You,” which, at the end of its 13-week reign, yielded to her solo hit “Free Mind,” which scored 22 weeks in charge.

With “Whatchu Kno About Me,” GloRilla achieves her third No. 1 on R&B/Hip-Hop Airplay. In addition to the incumbent and “TGIF,” she posted a five-week reign through “Tomorrow 2,” a collaboration with Cardi B, in 2022-23.

Sexyy Red, meanwhile, claims her maiden R&B/Hip-Hop Airplay No. 1. Before the current champ, the rapper previously had a career peak of No. 5 with “U My Everything,” a team-up with Drake, last September.

In reaching No. 1, “Whatchu Kno About Me” outdoes the chart peak of its Southern rap classic sample, Lil Boosie’s “Wipe Me Down,” featuring Foxx and Webbie, which reached No. 8 in 2007 and spent 31 weeks on the radio list.

Elsewhere, “Whatchu Kno About Me” wins a fifth straight week atop Rap Airplay following an 8% increase in audience and a second week at No. 1 on the spins-based Mainstream R&B/Hip-Hop Airplay chart (up 19% in plays for the week).
