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 162 mainstream top 40 stations.
Cabello previously crowned Pop Songs for two weeks beginning Feb. 18 with "Bad Things," alongside Machine Gun Kelly. As a member of Fifth Harmony (which she departed in December 2016), Cabello led Pop Songs when the group's "Work From Home," featuring Ty Dolla $ign, began a two-week rule that June 4.
Cabello is additionally just the fifth artist to post multiple Pop Songs No. 1s as a soloist while also having ruled the ranking with a group. She joins Beyoncé, Adam Levine, Gwen Stefani and Justin Timberlake.
With its Latin vibe (fueled by its new Spanglish mix with Daddy Yankee, the track debuted on the Dec. 2 Latin Pop Songs chart at No. 18), "Havana" "stands out in a big way and it raises its hand among all the noise of straight-ahead pop-sounding singles," Brian Kelly, program director of Pop Songs reporter WXSS Milwaukee (and Entercom top 40 format captain), recently told Billboard, adding that Luis Fonsi and Daddy Yankee's summer (and beyond) smash "Despacito," featuring Justin Bieber, "knocked down the door [for] this type of sound.
"What once seemed like an impossible fit all of a sudden makes sense."
