The 2017 Billboard Music Awards prompted a 37 percent sales gain for the songs performed on ABC’s May 21 broadcast, according to Nielsen Music. Among the most notable gainers: Cher, Celine Dion, Imagine Dragons, Ed Sheeran, Julia Michaels and Sam Hunt.

The songs performed on the three-hour show – not including newly released tracks from Camila Cabello and Miley Cyrus – sold a total of 332,000 downloads in the week ending May 25. That sum was up 37 percent compared to the tunes’ collective sales haul in the previous week: 243,000. A year ago, the 2016 edition of the show triggered a 35 percent sales increase.

Eight songs performed on the 2017 show earned increases of more than 100 percent each, including The Chainsmokers’ “Young” (vaulting 626 percent to 4,000 sold), Bruno Mars’ “Versace on the Floor” (up 395 percent to 7,000) and Drake’s “Gyalchester” (increasing 158 percent to 7,000).

Billboard Icon Award winner Cher’s one-two punch of “Believe” and “If I Could Turn Back Time” was a big winner, too. “Believe,” a four-week Billboard Hot 100 No. 1 in 1999, jumped 499 percent (to 4,000 sold) while “If I Could Turn Back Time,” a No. 3 hit in 1989, zoomed 578 percent (to 4,000).

Celine Dion’s rendition of the love theme from the film Titanic, “My Heart Will Go On” (performed to celebrate the 20th anniversary of the song and movie), nets a 393 percent sales gain. The tune, which topped the Hot 100 for two weeks in 1998, sold 6,000 downloads in the latest tracking frame, up from a little more than 1,000 in the previous week. “Heart’s” sales for the week was its largest in a little more than four years -- since the week ending Feb. 10, 2013, when it moved 7,000 downloads.

The week’s biggest-selling song that was performed on the show was Imagine Dragons’ “Believer,” which logged its best sales frame yet: 71,000 downloads (up 30 percent). Other big sellers from the show include Julia Michaels’ “Issues” (56,000; up 25 percent), Sam Hunt’s “Body Like a Back Road” (53,000; up 11 percent), Halsey’s “Now or Never” (34,000; up 28 percent), Jason Derulo’s “Swalla,” featuring Nicki Minaj (30,000; up 19 percent), and Ed Sheeran’s “Castle on the Hill” (30,000; up 35 percent).
