Belles' collaboration with the late Dolly Parton, "Son of Jolene," has debuted at No. 51 on Billboard's Country Airplay chart dated 12 September, marking Belles' first entry on the chart. Written as a sequel to Parton's 1974 country classic "Jolene," the track holds particular significance as Parton's final new recording released before her death on 25 August, giving the debut added poignancy for both the singer-songwriter and Parton's fans.

Belles co-wrote the song with Tyler Bank and Dan Harrison, and it reached Parton via her longtime producer Kent Wells, who liked the concept enough to feature on it herself. The song drew 1.3 million in airplay audience in the week of 28 August to 3 September, a 68% rise week-on-week, according to Luminate. Elsewhere on the chart, Luke Combs' "Be by You" held the top spot for a third week, while Lauren Alaina's "All My Exes," featuring Chase Matthew, climbed to No. 10, giving Alaina her fourth top 10 hit and Matthew his third.
