After seventeen weeks, “Old Town Road” from Lil Nas X is now the longest running #1 in the history of the Billboard Hot 100. It tops the record previously held by Mariah Carey and Boyz II Men’s “One Sweet Day” as well as Luis Fonsi, Daddy Yankee, and Justin Bieber’s “Despacito.”
“Old Town Road” was originally released independently in December 3rd, 2018. The song first hit #1 on the week ending April 13. Over the last 17 weeks, Lil Nas X has also released remixes of “Old Town Road” featuring Diplo, Mason Ramsey and Young Thug, and RM of BTS.
It was threatened this week by a Billie Eilish re-issue with Justin Bieber, but stayed atop the list.
