From Billboard:
Mark Ronson’s “Uptown Funk!,” featuring Bruno Mars, hits hallowed ground atop the Billboard Hot 100: It reigns for a 10th week, joining the exclusive club of leaders that have reigned for double-digit weeks.
“Funk!,” released on RCA Records, becomes just the 29th No. 1 in Hot 100 history to lead for at least 10 weeks. If 29 seems like a high number, that’s out of 1,041 leaders dating to the chart’s Aug. 4, 1958, debut. In other words, only 3 percent of all Hot 100 No. 1s, now including “Funk,” have logged rules of 10 weeks or more.
Some at-ten-tion-getting trivia: The first song to lead for at least 10 weeks? Debby Boone’s “You Light Up My Life,” for 10 frames in 1977. The last before “Funk”? Pharrell Williams’ “Happy,” which led for 10 weeks last year and went on to become the Hot 100’s No. 1 song of 2014. The song with the most weeks at the summit: Mariah Carey and Boyz II Men’s “One Sweet Day,” which ruled for 16 weeks in 1995-96.
