Plus, new top 10s for deadmau5, Marshmello & Bastille and Mark Ronson, Diplo & Dua Lipa.

The Chainsmokers churn out a sixth No. 1 on Billboard's Dance/Mix Show Airplay chart, as "Side Effects," featuring Emily Warren, rises 2-1 (on the list dated Sept. 22).

The duo earns its first topper since "Something Just Like This" (with Coldplay), which led for seven weeks in 2017. "Effects" is Warren's first leader, and second entry, after a fellow featured turn on The Chainsmokers and Tritonal's "Until You Were Gone" (No. 26, Jan. 2016).

Since The Chainsmokers' first hit No. 1 on Jan. 23, 2016, with "Roses" (featuring Rozes), no act has come close to matching their six crowns; seven acts share second place with two leaders each in that span. Backtracking to the chart's August 2003 beginning, The Chainsmokers are fifth among all acts for the most No. 1s, after Rihanna (12), Calvin Harris (11), David Guetta and Madonna (seven each).

Elsewhere on Dance/Mix Show Airplay, deadmau5 drives 16-4 with "Monophobia," featuring Rob Swire. It's the mouse-headed DJ's sixth top 10 and first in six years, since "The Veldt," featuring Chris James, vaulted to No. 5 in September 2012. "Monophobia" is singer Swire's second top 10, and second via a feature on a deadmau5 hit, following the chart-topping "Ghosts 'N Stuff" in May 2010.

Marshmello and Bastille also break into the Dance/Mix Show Airplay top 10, with "Happier" (22-10). The track is Marshmello's sixth top 10 and Bastille's second.

"Happier" holds at No. 2 on Hot Dance/Electronic Songs, earning top Airplay Gainer status for a third straight frame, each since its No. 7 debut on Sept. 1. The song drew 21.s million radio audience impressions (up 30 percent), 11.5 million U.S. streams (up 10 percent) and sold 11,000 downloads (up 44 percent) in the tracking week, according to Nielsen Music. It leads Dance/Electronic Digital Song Sales for a third week and Dance/Electronic Streaming Songs for a second frame.

Continuing with Hot Dance/Electronic Songs, Silk City and Dua Lipa leap 34-9 with "Electricity." The track, released Sept. 6, surges following its first full week of tracking. It becomes the first top 10 for Silk City, the duo of Mark Ronson and Diplo, and the third for Lipa. Additionally, sales of 9,000 downloads power its 17-2 vault on Dance/Electronic Digital Song Sales, while 5.2 million domestic streams spark "Electricity" to a No. 11 start on Dance/Electronic Streaming Songs.
