From Billboard:
Old Dominion's "One Man Band" ascends 2-1 on Billboard's Country Airplay chart dated Dec. 14 with 38.8 million audience impressions in the week ending Dec. 8, according to Nielsen Music.

The song, written by Josh Osborne and the group's Trevor Rosen, Matthew Ramsey and Brad Tursi, is the act's seventh Country Airplay No. 1 and sixth in a row. (Old Dominion also includes Whit Sellers and Geoff Sprung.)
On the airplay-, streaming- and sales-based Hot Country Songs chart, "Band" holds at its No. 2 high, also drawing 10.7 million streams and 7,000 sold in the week ending Dec. 5.
The song is the second single from Old Dominion's self-titled third studio LP, which debuted at No. 1 on Top Country Albums (Nov. 9) with 31,000 equivalent album units, including 19,000 in album sales. Launch single "Make It Sweet" led Country Airplay on May 4, marking the group's sixth No. 1.
Old Dominion scored its first Country Airplay No. 1 in November 2015, when "Break Up With Him" led for two weeks. Follow-up "Snapback" peaked at No. 2 in June 2016, followed by five consecutive leaders before "Band": "Song for Another Time" (December 2016; one week); "No Such Thing as a Broken Heart" (September 2017; one); "Written in the Sand" (February 2018; one); "Hotel Key" (September 2018, two); and "Sweet."
Now with six straight Country Airplay No. 1s, Old Dominion, which won for vocal group of the year at the Country Music Association Awards on Nov. 13, boasts the second-longest active run, after Luke Combs (seven). "Band" dethrones Combs' seventh consecutive No. 1, "Even Though I'm Leaving," which led for three weeks.
(Note that many of the songs on this week's Country Airplay chart decrease in audience, as several iHeartMedia stations held annual St. Jude Radiothons, raising funds for St. Jude Hospital, during the tracking week.)
SONY No. 1 FOR 2019 Both Old Dominion and Luke Combs are on the Sony Music Nashville (SMN) roster, which also includes Kane Brown, Miranda Lambert, Maren Morris, Brad Paisley and Chris Young, among others, and SMN is Billboard's Top Country Label of 2019, an honor that it claims for the first time since 2011. (That year, the company's lineup also included Kenny Chesney, now with Warner Music Nashville, and Carrie Underwood, who now records for Capitol Records.)
In 2012, Big Machine Label Group (BMLG) was the top country label, while Universal Music Group reigned for the next six years (2013-18).
For 2019, UMG finishes second, followed by, respectively, BMLG, Warner Music Nashville and Broken Bow Records.
Capitol Records, under the UMG umbrella, repeats as the year's top Country Airplay label, thanks to a roster that includes, among others, Underwood, Dierks Bentley, Luke Bryan, Jon Pardi and Keith Urban.
