Here's a look at all the Pop Songs No. 1 by members of One Direction. (Zayn departed the group, which is currently on hiatus, in 2015.)
"Adore You," one week to-date, April 11, 2020
"Strip That Down," featuring Quavo; two weeks, beginning Oct. 14, 2017
"Slow Hands," one week, Oct. 7, 2017
"Pillowtalk," two weeks, beginning May 7, 2016
(The Pop Songs chart, which began in 1992, measures total weekly plays, as tabulated by Nielsen Music/MRC Data, among its reporting panel of 169 mainstream top 40 stations.)
As a group, One Direction tallied 13 Pop Songs entries, in 2012-16, including four top 10s: debut smash "What Makes You Beautiful" (No. 3, 2012); "Story of My Life" (No. 4, 2014); "Drag Me Down" (No. 6, 2015); and "Perfect" (No. 10, 2016).
Only two other groups each feature even two soloists with Pop Songs No. 1s: Fifth Harmony and Destiny's Child. 5H's Camila Cabello has achieved four leaders and Normani has notched one, while the group also earned one: "Work From Home," featuring Ty Dolla $ign, in 2016.
Apart from Destiny's Child, Beyoncé has banked six solo Pop Songs No. 1s and Kelly Rowland has scored one. The act collected two No. 1s: "Jumpin', Jumpin' " and "Independent Women Part 1," in 2000-01.
Meanwhile, Louis Tomlinson could make for a clean sweep as far as One Direction members topping Pop Songs. So far, he's reached a No. 25 high with "Back to You," featuring Bebe Rexha and Digital Farm Animals, in 2017. Late last year, he tallied his first Pop Songs entry without any accompanying acts: "We Made It" debuted in December and reached No. 32 in January.
