Thanks to "Stay," Rihanna is the first artist in the 20-year history of Billboard’s Pop Songs radio airplay chart to have 10 No. 1 hits.
The singer's pop ballad with Mikky Ekko pushed her past Katy Perry, who has racked up nine No. 1s since 2008.
As Billboard notes, “Stay” is the second piano-and-vocal-only hit (out of 259 songs) to reach No. 1 on the chart. Bruno Mars’ “When I Was Your Man” is the first.
