Rihanna becomes the first artist in the 20-year history of Billboard's Nielsen BDS-based Pop Songs radio airplay chart to tally 10 No. 1s, as Stay, featuring Mikky Ekko, rises 2-1.

Rihanna breaks a tie with Katy Perry, who's notched nine No. 1s since her 2008 arrival; also impressively, Rihanna has rung up her No. 1 sum since just 2006, when SOS, her first leader, reached the summit. She'd last led with We Found Love, featuring Calvin Harris, for eight weeks, marking her longest command, in late 2011/early 2012.

The record for most No. 1s is the latest for Rihanna on Pop Songs. She previously established the marks for most entries (35) and top 10s (23) dating to the ranking's Oct. 3, 1992, launch.
