Rihanna has scored her tenth #1 single with her “S&M” remix featuring Britney Spears. She is now tied with Janet Jackson and Stevie Wonder, as they all hold the 7th position amongst all artists with the most chart-toppers in the history.
Mariah Carey remains the solo artist with the most #1 singles: 18!
However, Rihanna surpassed Mariah Carey in two other titles: achieving 10 #1 songs faster than any solo act and being the youngest person to accomplish that feat thus far. SOURCE
Sooo, Rihanna did in 6 years what Janet did in 30? Interesting industry.
