In the 2016 chart year, The Chainsmokers held the No. 1 spot on Hot Dance/Electronic Songs for a seemingly unbeatable 39 weeks, but leave it to them to beat it. During the 2017 chart year (encompassing the chart weeks from Dec. 3, 2016, through Nov. 25, 2017), The Chainsmokers triumphed for 41 total weeks.
"Closer" completed its 27-week run at No. 1 (counting 13 weeks in the 2016 chart year and 14 in 2017) on March 4, setting a new longevity record: Since the chart's Jan. 26, 2013 inception, "Closer" has spent more weeks at No. 1 than any other song, besting Avicii's "Wake Me Up!" (26 weeks, 2013-14).
Next, the DJ duo dethroned itself, earning two weeks at No. 1 with "Paris," beginning on March 11. The following week, the act replaced itself at the top for a third straight week, with "Something," which went on to log a whopping 25 weeks at No. 1.
The Chainsmokers now lead all acts with six total Hot Dance/Electronic Songs No. 1s. Calvin Harris (whose "Feels," featuring Pharrell Williams, Katy Perry and Big Sean, spent three weeks at No. 1 in 2017) is next with four.
The Chainsmokers also end 2017 as the leading Dance/Electronic Streaming Songs Artist, Dance/Electronic Digital Song Sales Artist, Dance/Mix Show Airplay Artist and Top Dance/Electronic Albums Artist. Plus, the act's first full-length album, Memories…Do Not Open, completes the year as the No. 1 Dance/Electronic Album, while its two EPs both make the year-end list: Collage at No. 2 and Bouquet at No. 13. On Dance/Electronic Streaming Songs, The Chainsmokers lock in the top three titles (in order): "Closer," "Something" and "Don't Let Me Down," featuring Daya.
Calvin Harris follows The Chainsmokers as the No. 2 Top Dance/Electronic Artist of 2017. The superstar DJ/producer's album Funk Wav Bounces Vol. 1 is No. 3 on the Top Dance/Electronic Albums list, behind only The Chainsmokers' Memories and Collage, and two Funk tracks finish in the Hot Dance/Electronic Songs top 10: "Slide" (featuring Frank Ocean and Migos, No. 8) and "Feels" (No. 10).
Marshmello concludes 2017 as the Top Dance/Electronic New Artist (and the 11th overall act), powered by 10 tracks and one leader on Hot Dance/Electronic Songs. "Wolves," credited to Selena Gomez X Marshmello, hit No. 1 on Nov. 18. (His "Silence," featuring Khalid, would go on to top the chart on Dec. 2, a week after the completion of the chart year.)
"Silence" also topped three other dance charts in 2017: Dance/Electronic Streaming Songs (Sept. 2), Dance/Electronic Digital Song Sales (Nov. 4) and Dance Club Songs (Nov. 25). On Dance/Mix Show Airplay, "Silence" reached No. 2. Marshmello finishes the year as the No. 3 Dance/Electronic Streaming Songs Artist, thanks not only to the success of "Silence" (11 weeks at No. 1 in the chart year) but also to a host of other tracks, including "Alone."
Kygo this year continued his success from 2016, when he was the No. 2 Dance/Electronic New Artist, scoring a monster hit with his Selena Gomez collaboration "It Ain't Me." The track finishes 2017 at No. 4 on Hot Dance/Electronic Songs, having remained in the top 10 since its March 4 debut at No. 9. While many songs dip after a big debut week, "Ain't" marched upward, first reaching its No. 2 peak on May 13. Only Clean Bandit's "Rockabye," featuring Sean Paul and Anne-Marie, spent more weeks than "Ain't" in the top 10 during the chart year (48 vs. 39). Kygo wraps the year as the No. 5 Top Dance/Electronic Artist.
Rihanna ruled the Dance Club Songs summit more than anyone else in 2017, earning an unprecedented five No. 1s in a calendar year and finishing as the No. 1 Dance Club Songs Artist. She reigned with "Desperado" (Oct. 14), "Wild Thoughts" (by DJ Khaled featuring Rihanna and Bryson Tiller, Aug. 26), "Pose" (July 15), "Sex With Me" (April 8) and "Love on the Brain" (Jan. 21). Of those, two end 2017 in the top 10 ("Love," No. 3, and "Pose," No. 8) and all five finish in the top 50, the most of any act. Rihanna's ANTI album became the first to yield seven No. 1s since the original edition of Katy Perry's Teenage Dream in 2010-12. With 32 total toppers, Rihanna trails only Madonna's 46 No. 1s since the chart's Aug. 28, 1976, inception as a national chart.
However, it was Ed Sheeran who finishes the year with the No. 1 track on Dance Club Songs, "Shape of You." Fittingly, it was the only song to lead the chart for multiple weeks, spending two frames atop the list (March 18 and 25). The feat echoes that of last year's No. 1, "This Is What You Came For," by Calvin Harris featuring Rihanna, which topped the tally for two weeks in July 2016. "Shape" combined with Sheeran's "Castle on the Hill," which peaked at No. 2 for two weeks in July, to make Sheeeran the year's No. 3 Dance Club Songs Artist.
"Shape" also shakes out as 2017's No. 1 title on Dance/Mix Show Airplay, where Sheeran ranks as the No. 2 act. (The Dance/Mix Show Airplay chart measures radio airplay on a select group of full-time dance stations, along with plays during mix shows on over 80 top 40-formatted reporters.) "Shape" spent six weeks at No. 1.
Billboard's year-end music recaps are based on chart performance between the Dec. 3, 2016 and Nov. 25, 2017-dated charts. Data registered before or after a title's chart run are not considered in these standings. That methodology detail, and the December-November time period, account for some of the differences between these lists and the calendar-year recaps that are compiled independently by Nielsen Music.
