The top spot on the ranking of the artists with the most No. 1 Hot 100 hits hasn’t changed in 45 years, with the Beatles (20 leaders, tallied in 1964-70) fending off closest competitor Mariah Carey (18). Notably, Rihanna has entered a tie, with Michael Jackson, for the third-most Hot 100 No. 1s (13), all since her first, “SOS,” in 2006.
The list of acts with the most Hot 100 No. 1s was compiled from the chart’s Aug. 4, 1958 inception through the chart dated Oct. 10, 2015.
