Other highlights of Khalid and Normani's coronation:
Longest trip to No. 1 for a duet: Reigning in its 24th week on Pop Songs, "Love Lies" completes the longest journey to No. 1 for a song by two equally-billed lead acts. It passes the 17-week ascent by Major Lazer and DJ Snake's "Lean On," featuring MO, in 2015.
Among all songs, only three have made longer runs to No. 1 than "Love Lies," led by Cara's "Here" (26 weeks, 2015-16).
First soundtrack No. 1 since 2016: "Love Lies," from the Love, Simon soundtrack (and released on Fox/RCA Records), is the first song released from a soundtrack to top Pop Songs since Justin Timberlake's "Can't Stop the Feeling!," from Trolls, for three weeks beginning June 18, 2016.
5H Joins 1D & Destiny's Child: Normani is the second member of Fifth Harmony (now on hiatus) to rule Pop Songs. Camila Cabello (who departed the group in December 2016) boasts three No. 1s: "Bad Things," with Machine Gun Kelly (two weeks, 2017); "Havana," featuring Young Thug (seven, 2017-18); and "Never Be the Same" (three, 2018).
5H is the third group to spin off at least two chart-topping members on Pop Songs. One Direction (which has never led the list) set the mark with three: (former member) Zayn (one No. 1), Niall Horan (one) and Liam Payne (one). Apart from Destiny's Child, owners of two Pop Songs No. 1s, Kelly Rowland has scored one solo leader and Beyoncé, six.
Plus, Ariana Grande debuts at No. 38 on Pop Songs with "Breathin," the third track to reach the chart from her album Sweetener, which debuted at No. 1 on the Sept. 1-dated Billboard 200. The first two remain in the Pop Songs top 10: "God Is a Woman," up 9-8 (a new peak), and former No. 1 lead single "No Tears Left to Cry," which holds at No. 10.
"God" makes the chart's third-greatest gain (up 11 percent in plays, according to Nielsen Music), but Republic Records is already concurrently promoting "Breathin," as labels are considering whether to space single releases more closely together in era when fans can stream any song from an album upon its release.
All charts will update tomorrow (Sept. 18) on Billboard.com.
