Rihanna Sets Record For Most Mainstream Top 40 #1s

From Billboard:

Rihanna becomes the first artist in the 20-year history of Billboard’s Nielsen BDS-based Mainstream Top 40 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 rang 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.

2006, “SOS” (one week at No. 1)
2008, “Take a Bow” (three)
2008, “Disturbia” (three)
2008, “Live Your Life” (T.I. feat. Rihanna) (two)
2010, “Rude Boy” (two)
2010, “Love the Way You Lie” (Eminem feat. Rihanna) (two)
