Sombr ascends to No. 1 on Billboard’s Hot Rock Songs chart for the first time, lifting a spot on the Aug. 16-dated tally with “Undressed.”

The track registered 8.7 million official streams (up 6%), 29.2 million radio audience impressions (up 1%) and 1,000 sold (up 9%) in the United States in the week ending Aug. 7, according to Luminate.

“Undressed” takes over from Hozier’s “Too Sweet,” which dominated for a chart-record 70 weeks, including every frame until this week since the list dated June 15, 2024.

Music by sombr comprises the chart’s top two, as “Back to Friends” also rises one position, driven by 12.3 million streams and 5.9 million in radio reach. He’s the first artist to claim the winning and runner-up ranks simultaneously since Zach Bryan on the Oct. 7, 2023, chart with “I Remember Everything” (featuring Kacey Musgraves; No. 1) and “Sarah’s Place” (featuring Noah Kahan; No. 2).

Concurrently, “Undressed” and “Back to Friends” both lift a spot to Nos. 2 and 3, respectively, on Hot Rock & Alternative Songs. On the all-genre Billboard Hot 100, “Undressed” climbs 30-28 after reaching No. 25 in June, while “Back to Friends” rises 32-30, a new peak.

“Back to Friends” is No. 1 on the Rock Streaming Songs and Alternative Streaming Songs charts for an eighth and ninth week, respectively. After ruling the Alternative Airplay chart for five weeks, it’s crossing over to pop radio, reaching new highs of No. 33 on Adult Pop Airplay and No. 34 on Pop Airplay.

“Undressed” has taken the opposite approach at radio. It first surfaced at pop formats and hits a new best of No. 5 on Adult Pop Airplay while holding at its No. 6 high on Pop Airplay. It ranks at No. 34 on Alternative Airplay after reaching No. 29 the previous frame.

The Hot 100 also welcomes sombr’s newest release, “12 to 12,” at No. 95. It bowed at No. 16 on the Hot Rock Songs chart dated Aug. 9 and rises to No. 13 on the latest list.

Sombr’s breakout tracks are part of his debut Warner Records album, I Barely Know Her, due Aug. 22.
