The song is her highest-charting hit since "Cool for the Summer," and could soon pass that song's peak. Plus, moves for 21 Savage, Ed Sheeran, Maroon 5 & Halsey.

As previously reported, Taylor Swift's "Look What You Made Me Do" spends a second week at No. 1 on the Billboard Hot 100 chart (dated Sept. 23). Swift also blasts in at No. 4 with "…Ready for It?," with both songs previewing her new album Reputation, due Nov. 10.

Meanwhile, Cardi B climbs 3-2 with "Bodak Yellow (Money Moves)," marking the first time in nearly three years that solo women (in lead roles) rank at Nos. 1 and 2 simultaneously on the Hot 100.

Beyond all those achievements, who else (both men and women) makes notable Hot 100 chart moves this week?

"Bank Account," 21 Savage
Let's start with a mini-"Ask Billboard," from reader John Howarth, who wonders: "Can 'Bank Account' become the song to spend the most weeks peaking at No. 12 on the Hot 100?"

This week, the track logs its fifth consecutive week at its No. 12 high. Only one song has totaled more time at No. 12, although it peaked at No. 10: Elle King's "Ex's & Oh's," six weeks in 2015. If "Bank Account" peaks at No. 12, it would claim the record for most weeks spent peaking at the rank, passing four songs that tallied four weeks each at the position: Drake and Future's "Jumpman" (2015); Calvin Harris' "Feel So Close" (2012); Alice Cooper's "How You Gonna See Me Now" (1978); and High Energy's "You Can't Turn Me Off (In the Middle of Turning Me On)" (1977).

Then again, "Bank Account" could still cash in with a higher peak, as it's been bulleted in each of its five weeks at No. 12 and gains in all metrics this week. It's led by its No. 4 rank on the Streaming Songs chart with 32.3 million U.S. streams (up 6 percent) in the tracking week, according to Nielsen Music.

"Shape of You," Ed Sheeran
The former 12-week Hot 100 No. 1 dips 11-16 after spending its first 33 weeks in the top 10, rewriting the record for the most weeks spent in the region. Still, "Shape" continues its reign atop the Adult Contemporary radio airplay chart, where it spends a 21st week at No. 1, tying for the third-longest command since the list launched in 1961.

Weeks at No. 1, Title, Artist(s), Date Reached No. 1
28, "Drift Away," Uncle Kracker feat. Dobie Gray, June 7, 2003
22, "Hey, Soul Sister," Train, July 3, 2010
21, "Shape of You," Ed Sheeran, May 6, 2017 (through the chart dated Sept. 23)
21, "Hello," Adele, Nov. 28, 2015

21, "A New Day Has Come," Celine Dion, March 30, 2002
20, "Just the Way You Are," Bruno Mars, Feb. 5, 2011

Meanwhile, "Shape" follow-up single "Perfect" debuts at No. 34 on the Adult Pop Songs airplay chart. (Also new on Adult Pop Songs, two singles that should make splashes with debuts on next week's Hot 100, dated Sept. 30, following their first full weeks of data tracking: Kelly Clarkson's "Love So Soft," which enters Adult Pop Songs at No. 22, and Sam Smith's' "Too Good at Goodbyes," which bows at No. 26.)

"Sorry Not Sorry," Demi Lovato
Lovato has her highest-charting Hot 100 hit since "Cool for the Summer," which reached No. 11 in 2015, as "Sorry" surges 18-13. It gains in all metrics, up 21 percent to 33 million in all-format radio audience; 12 percent to 20 million U.S. streams; and 2 percent to 53,000 downloads sold.

"What Lovers Do," Maroon 5 feat. SZA
Following its first full week of tracking, the single vaults 73-27 on the Hot 100 (marking Maroon 5's 19th top 40 Hot 100 hit). It ranks at No. 12 on Digital Song Sales with 32,000 sold and No. 32 on Radio Songs (38 million impressions).

"Bad at Love," Halsey
The follow-up to the No. 17-peaking "Now or Never" debuts at No. 81 on the Hot 100. On Pop Songs, it pushes 30-26, up 36 percent in plays. Both songs are from hopeless fountain kingdom, which arrived as Halsey's first No. 1 on the Billboard 200 in June.
