The Chainsmokers Take '#SELFIE' to No. 1 on Dance Chart

The Chainsmokers take a selfie in their video for "#Selfie."

The Chainsmokers' surge up Billboard's Hot Dance/Electronic Songs chart with "#SELFIE" culminates in the track taking over the top spot (5-1).

"#SELFIE" (featuring an uncredited vocal from Alexis Killacam) reigns with Airplay and Digital Gainer honors, also bolting up Dance/Electronic Streaming Songs (16-7; 1.4 million U.S. streams, according to Nielsen BDS), Dance/Mix Show Airplay (4-2), Dance Club Songs (33-19) and the Billboard Hot 100 (28-18). It ranks at No. 1 for a second week on Dance/Electronic Digital Songs (111,000 downloads sold, up 26 percent, according to Nielsen SoundScan).

The Chainsmokers' march to No. 1 took only five weeks, the fastest flight since Lady Gaga's "Applause" needed only two frames last August.

With "Hey Brother" sliding to No. 2 after a week at No. 1, Avicii's unprecedented 27-week lock on the Hot Dance/Electronic Songs summit is broken. The streak began the week of Sept. 21, when "Wake Me Up!" began its record 26-week rule.

'SUMMER' TIME: Just in time for spring (finally), Calvin Harris debuts at No. 26 on Hot Dance/Electronic Songs with "Summer." The first song from Harris' forthcoming album features his vocals for the first time.

The start is based on a split of radio airplay (3.1 million audience impressions) and streams (215,000), while sales will impact the chart next week following the song's March 15 digital release.

'DOWN' IS UP: DJ Snake & Lil Jon improve with "Turn Down for What," the Streaming Gainer on Hot Dance/Electronic Songs (3-3) and the Hot 100 (27-21). Following the premiere of its video, it cruises 5-2 on Dance/Electronic Streaming Songs (2.9 million, up 61 percent). "Turn" also increases on Dance/Electronic Digital Songs (2-2; 83,000, up 10 percent) and Dance/Mix Show Airplay (12-9).

SHINING 'LIGHTS': Tiesto scores his first Hot Dance/Electronic Songs top 10, as "Red Lights" lifts 11-10. The track also becomes his first unaccompanied hit on the Hot 100, debuting at No. 97. The Dutch DJ previously charted on the Hot 100 with Three 6 Mafia, Sean Kingston and Flo Rida on the No. 78-peaking "Feel It" four years ago.

Still, Tiesto is no stranger to Billboard charts, having placed seven songs on Dance Club Songs (beginning with  in 2001) and 11 on Dance/Mix Show Airplay. "Lights" is a hit on both lists, up 5-3 on Dance Club Songs and leading Dance/Mix Show Airplay for a fifth week. Tiesto tallied one prior Dance/Mix Show Airplay No. 1: 2009's "I Will Be Here," with Sneaky Sound System.

ROKELLE REIGNS: Rokelle rejoices in her first Dance Club Songs No. 1, while featured artist Dave Aude enjoys his eighth, as "Take Me Away" rises 2-1. Remixes from Denzal Park, Ivan and Nacho and Aude himself, among others, helped propel the track to No. 1.
