Question: what is the longest #1 single on billboard?
Answer: “Old Town Road” is now much more than an inescapably catchy song — it's a history-maker. At 17 weeks at the top of the Billboard Hot 100 chart, which tracks the sales and streaming data of music's biggest singles, Lil Nas X's genre-redefining hit has become the longest-running No. 1 single in Billboard's history.
