Sia Continues Her ‘Unstoppable’ Run With 6-Year-Old Hit, But Just How High Can It Go?

This week, Sia‘s “Unstoppable” tops yet another new Billboard chart — six years after it was released.

The anthemic hit, which was on Sia’s 2016 album This Is Acting alongside the Billboard Hot 100 No. 1 “Cheap Thrills,” has found new life over the past year, and this week, it rises 2-1 on the Adult Contemporary airplay chart. Last month, the song topped the Adult Pop Airplay chart too, and it’s so far peaked at No. 28 on the Hot 100.

Just how high can this revived song climb? On the latest Billboard Pop Shop Podcast (listen below), Katie & Keith discuss its unlikely trajectory and what has driven its “Unstoppable” recent run on our charts.

Also on the show, we’ve got chart news on how both Rihanna’s “Lift Me Up” and SZA’s “Shirt” make high debuts on the Hot 100, how Taylor Swift’s Midnights logs a second — big! — week at No. 1 on the Billboard 200 albums chart, and how the latest expanded reissue of a classic Beatles album returns to the Billboard 200 top 10. We also discuss the Billboard chart legacy of Aaron Carter, the pop star, TV personality and brother of Backstreet Boys’ Nick Carter, who died over the weekend at age 34.
