Kendrick Lamar’s “Not Like Us,” enters the record books with an unprecedented 21st week at No. 1 on Billboard’s Hot Rap Songs chart. The single, released on pgLang/Interscope/ICLG, surpasses Lil Nas X’s 2019 juggernaut, “Old Town Road,” featuring Billy Ray Cyrus, for the most weeks atop the chart since its launch in 1989.

“Not Like Us,” released May 4 amid the height of the rappers’ feud, reaches the record through continued strong performance in the three metrics that inform the chart: streaming, sales and radio airplay.

It wins a 20th slot at No. 1 on the Rap Streaming Songs chart thanks to 17.1 million official U.S. streams in the latest tracking week (Sept. 27 – Oct. 3), according to Luminate.

With its newest week on top, it matches “Old Town Road” for the third-longest command among all titles. Desiigner’s “Panda” and Psy’s “Gangnam Style,” share first place, at 23 weeks each.

For sales, “Not Like Us” registered 2,000 downloads in the tracking week. Despite a 10% decline from the prior week, it pushes 4-3 on Rap Digital Song Sales, a list it previously ruled for nine nonconsecutive weeks.

Lamar’s smash also repeats at No. 7 on the all-genre Radio Songs chart, with 45.4 million in total audience impressions, a 3% slide. (All radio airplay, regardless of genre, contributes to a song’s rank on Hot R&B/Hip-Hop Songs.) The single dominated its core format this summer, with 15 nonconsecutive weeks in charge of the R&B/Hip-Hop Airplay list.

Here’s a review of the songs with the most weeks at No. 1 in the chart’s 35-year history:

The colossal single extends Lamar’s recent near-monopoly on Hot Rap Songs, with the rapper in the No. 1 spot for 27 of the last 28 weeks. Before “Not Like Us” took the throne, the Pulitzer Prize winner, Future and Metro Boomin ruled with their collaboration “Like That,” a six-week champ. In the past six months, only Eminem’s “Houdini” interrupted the Lamar blockade, by sneaking out a one-week rule in June. S: Billboard
