Katy Perry parades to her 19th No. 1 on Billboard's Dance Club Songs chart, as "Never Really Over" rises 3-1 on the list dated Sept. 21.
Perry boasts the fifth-most leaders dating to the chart's August 1976 inception as a national survey, trailing only Madonna (48 No. 1s), Rihanna (33), Beyoncé (22) and Janet Jackson (20).

"Never" was remixed by R3hab, Syn Cole and Wow & Flutter, among others.
On Top Dance/Electronic Albums, Lindsey Stirling storms in at No. 1 with Artemis, which launches with 19,000 equivalent album units earned, according to Nielsen Music, nearly all from album sales. Artemis is Stirling's fourth leader on the list, following Brave Enough (2016), Shatter Me (2014) and Lindsey Stirling (2012).
Looking at Hot Dance/Electronic Songs, Steve Aoki's "Let It Be Me," featuring Backstreet Boys, starts at No. 12. It's Aoki's 25th appearance and the first for the Backstreet Boys. "Let" begins with 1 million U.S. streams and 7,000 downloads sold and opens at No. 1 on Dance/Electronic Digital Song Sales, marking Aoki's second leader and the Boys' first.
