The song matches the stay of Edwin McCain's "I'll Be" 20 years ago.
Rounding out the five longest-charting Pop Songs hits are three that each totaled 39 weeks: Goo Goo Dolls' "Slide" and "Iris" (both in 1998-99) and Real McCoy's "Another Night" (1994-95; the No. 1 song of the chart's first 25 years).
The Pop Songs survey measures total weekly plays, as tabulated by Nielsen Music, among its reporting panel of 158 mainstream top 40 stations.
Lipa additionally joins Iggy Azalea (in 2014) as the only women to chart three songs simultaneously in the Pop Songs chart's top 15: Along with "Rules" at No. 13, "One Kiss," with Calvin Harris, and her own "IDGAF" each rise a notch, to new highs of Nos. 14 and 15, respectively.
"Dua Lipa has developed into quite the pop radio force," says WBBM-FM (B96) Chicago assistant program director/music director Erik Bradley; the station leads all Pop Songs reporters with over 3,500 plays of "Rules" to date. The track "just will not go away," he muses. "It's consistently top five in all of our key research demos.
"It's the kind of song that pop radio needs to continue to thrive: great vocal, strong lyric, good tempo … the recipe for a classic pop song."
