NEW YORK (NYTimes) - 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, a 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 a lesson in the state of music marketing: Lil Nas X's Old Town Road.
After its latest blast of remixes and videos, it notched its 17th week on Monday (July 29) atop Billboard's flagship singles chart.
Although the song's lead has been slipping in recent weeks - Billie Eilish's Bad Guy had twice as many radio plays as Old Town Road - it was enough to lead Lil Nas X to a historic run.
Since it first topped the chart in April, the song consistently had huge numbers.
It has blocked new songs by giants like Taylor Swift, Ed Sheeran, Eilish and Shawn Mendes from reaching No. 1.
And the song has been a pervasive cultural phenomenon for much of the year, with an endless series of online memes - many generated by Lil Nas X.
The rise of Old Town Road - and the week-by-week maintenance of its chart position - is in some ways a story of an old-fashioned one-hit wonder, and in some ways a primer on the latest and most effective ways that music is promoted.
Almost from the moment that Lil Nas X released the song late last year, as an independent act, it was an experiment in both genre and viral marketing.
He began generating social-media memes for Old Town Road, and the song first became a hit on video sharing app TikTok.
Thousands of young people made short clips mugging in cowboy hats and boots with Lil Nas X's song playing in the background, tagging their clips #yeehaw.
By mid-March, he had signed to Columbia Records and first hit the mainstream news radar after Billboard removed the song from its Hot Country Songs chart, drawing criticism about the conservatism of country radio and accusations of racism.
But what made Old Town Road a lasting hit was its steady and strategic drip of remixes. The first, with Billy Ray Cyrus, sent the song to No. 1 in April.
Then came Diplo's electronic version; another with rapper Young Thug and Mason Ramsey, the 12-year-old "Walmart yodelling kid", who was summoned awake one night to record his verse; and RM of K-pop group BTS.
