The longest-running No. 1 single in the 61-year history of Billboard’s Hot 100 chart is not by Elvis Presley, the Beatles, Michael Jackson or Madonna.

And no longer is that record held by “One Sweet Day” by Mariah Carey and Boyz II Men, from 1995, or “Despacito,” the 2017 Latin smash by Luis Fonsi, with Daddy Yankee and Justin Bieber — both of which held the top spot for 16 weeks.

The new champion is as much a novelty song as it is a meme and an object lesson in the state of music marketing: Lil Nas X’s “Old Town Road,” which — after its latest blast of remixes and videos — on Monday notched its 17th week atop Billboard’s flagship singles chart.
