Ella Langley, the Alabama-born country singer-songwriter whose song “Choosin’ Texas” has been a monster hit all summer, has broken a Billboard chart record after holding off some unexpected competition from Dolly Parton. “Choosin’ Texas,” a twangy romance about a love triangle caught between Tennessee and Texas, notched its 20th week at No. 1 on the Billboard Hot 100, the publication announced Monday. That is a record for a non-holiday song, surpassing Lil Nas X’s “Old Town Road” and Shaboozey’s “A Bar Song (Tipsy),” which each held the top spot for 19 weeks. Mariah Carey’s “All I Want for Christmas Is You” (1994), which took 25 years to reach No. 1 for the first time, has racked up the most total weeks for any song in the 68-year history of Billboard’s flagship, all-genre singles chart, with 22.

At a time when many country hits involve collaborations and crossovers from other genres, “Choosin’ Texas” is a straight-up, Nashville-style hit, which Langley, 27, wrote in collaboration with Miranda Lambert and others. Released in October, the song first reached No. 1 on the Hot 100 in February and has been a steady hit ever since. In recent weeks, Langley had seemed destined to hit the chart milestone.

But that sense of inevitability was briefly shaken by the death of Parton on Aug. 25, in the middle of the industry’s sales week. Two classics by Parton, “Jolene” and “9 to 5,” rapidly shot up the streaming charts as the news spread. On the day Parton died, streams for “Jolene” in the United States rocketed about 1,600 percent compared to the day before, according to Luminate, the tracking service that supplies data to Billboard for its charts.

But that rise was not enough to overcome the consumption of Langley’s track over the full week. To compute chart positions for the Hot 100, Billboard and Luminate, its data partner, use a formula that, in addition to streaming, looks at track downloads and radio play. Over the last week, “Choosin’ Texas” had 24.2 million official streams in the United States, largely unchanged from the week before, as well as 56.8 million “airplay audience impressions,” a measurement of its popularity on the radio, Billboard reported.

It also sold about 7,000 copies as digital downloads. Country has performed very well in the top rungs of the Hot 100 recently. This week, the rest of the top four slots are all country songs, holding their positions from last week: Stella Lefty’s “Boston” is No. 2; Taylor Swift’s “I Knew It, I Knew You,” from “Toy Story 5,” is No. 3; and Morgan Wallen’s “Been by Now” is No. 4.

Parton’s “Jolene” landed at No. 16 on this week’s Hot 100 along with “I Will Always Love You” at No. 27. “Jolene” went to No. 1 on the country chart in early 1974, though on the Hot 100 it went only as high as No. 60.
