Selena Gomez and Marshmello march 7-1 on Billboard's Hot Dance/Electronic Songs chart (dated Nov. 18) with "Wolves," following its first full tracking week. (It debuted a week ago with a day's worth of streaming and sales data.)

Gomez, Billboard's 2017 Woman of the Year honoree, earns her second No. 1 and first as a lead act, after "I Want You to Know" (by Zedd featuring Gomez), which spent six weeks at No. 1 in March and April 2015. "Wolves" is Marshmello's first leader on the list.

"Wolves" reigns with 13 million U.S. streams, 8 million in all-format radio audience and 28,000 downloads sold, according to Nielsen Music. It holds at No. 1 on Dance/Electronic Digital Song Sales and soars 13-2 on Dance/Electronic Streaming Songs, behind Marshmello's "Silence" (featuring Khalid) in the latter's 10th week at the top.
