Among all acts, "Havana" is just the ninth song to have hit No. 1 on the Pop Songs, Rhythmic Songs and Adult Pop Songs airplay charts (over the 22 years that all three lists have coexisted). Here's a chronological recap:
"One Sweet Day," Mariah Carey & Boyz II Men, 1995-96
"Livin' La Vida Loca," Ricky Martin, 1999
"Mirrors," Justin Timberlake, 2013
"Blurred Lines," Robin Thicke feat. T.I. + Pharrell, 2013
"Happy," Pharrell Williams, 2014
"All of Me," John Legend, 2014
"Am I Wrong," Nico & Vinz, 2014
"Uptown Funk!," Mark Ronson feat. Bruno Mars, 2015
"Havana," Camila Cabello feat. Young Thug, 2017-18
The Pop Songs chart, which began in 1992 (and just celebrated its 25th anniversary), measures total weekly plays, as tabulated by Nielsen Music, among its reporting panel of mainstream top 40 stations. Rhythmic Songs (also launched in 1992) reflects airplay on rhythmic stations that span pop to R&B/hip-hop, while Adult Pop Songs (begun in Billboard magazine in 1996) ranks songs on adult top 40 stations.
(Notably, seven of the nine multi-format No. 1s above have joined the exclusive club in the past five years. That could be attributed partly to the adult pop format's lean this decade toward a more mainstream pop sound after years of favoring pop-rock, as such acts as Maroon 5, Katy Perry, P!nk and Taylor Swift have supplanted a host of guitar-based bands.)
Cabello earns her first Adult Pop Songs No. 1. As a member of Fifth Harmony, which she departed in December 2016, she rose as high as No. 18 on the chart with the group's "Work From Home," featuring Ty Dolla $ign, that July.
"Havana" previously topped the all-genre, streaming-, airplay- and sales-based Hot 100 dated Jan. 27, the same week that her debut solo album Camila debuted at No. 1 on the Billboard 200.
Meanwhile, "Havana" follow-up "Never Be the Same," which has reached No. 27 on the Hot 100 (Feb. 17), climbs 15-14 on the March 3-dated Pop Songs chart, 24-22 on Rhythmic Songs and 30-28 on Adult Pop Songs.
