The 2013 Billboard Music Awards pump big sales gains on the charts this week, thanks to blockbuster performances from the likes of Bruno Mars, Jennifer Lopez and Ed Sheeran. The show aired on May 19 from 8-11 PM on ABC.

In the week ending May 19, the broadcast spurred an overall 15% gain for the 18 previously-released songs performed on the broadcast, according to SoundScan. That increase handily beat the overall song download market’s 1% gain this past week — an impressive feat considering there were only a few hours left in the tracking week before the close of business on Sunday night.

Combined, the 18 tunes sold 842,000 downloads — up from the 733,000 the week previous. Those songs include Mars’ “Treasure” (24,000; up 220%), Lopez’s “Live It Up” (65,000; up 53%) and Sheeran’s “Lego House” (56,000; up 134%).

“Treasure,” which is the third single from Mars’ Unorthodox Jukebox album, also debuts on the Billboard Hot 100 chart at No. 71. It follows the album’s two previous No. 1s: “Locked Out of Heaven” and “When I Was Your Man.”

Other gaining songs include Chris Brown’s “Fine China” (35,000; up 41%), Selena Gomez’s “Come and Get It” (164,000; up 15%), will.i.am’s “#thatPower,” featuring Justin Bieber (81,000; up 3%) and David Guetta’s “Play Hard,” featuring Akon and Ne-Yo (12,000; up 164%).

Even a-ha’s classic Billboard Hot 100 No. 1 hit “Take On Me” earned a 30% gain, following its surprise performance on the show. The group’s singer, Morten Harket, joined Pitbull and Christina Aguilera during their rendition of “Feel This Moment,” which samples “Take On Me.” The latter cut moved 3,000 downloads for the week.
