The only artists with more top 10s than that quartet since the Hot 100 originated with the chart dated Aug. 4, 1958? Madonna (38), the Beatles (34), Michael Jackson (29) and Stevie Wonder (28). (Notably, Elvis Presley boasts 25 Hot 100 top 10s, but his career predated the chart by two years; had the chart existed earlier, his top 10 count would be higher.)
Especially impressive, Rihanna has reached 27 Hot 100 top 10s faster than any other soloist. Dating from an artist's first week on the Hot 100 to the frame in which it notched its 27th top 10, only one act has reached the sum more quickly: the Beatles tallied their 27th top 10 (1969's "Get Back," with Billy Preston) a mere five years, three months and three weeks after their 1964 Hot 100 debut with "I Want to Hold Your Hand" (their first Hot 100 charted title, top 10 and No. 1).
