This announcement follows a surprising and exciting year for the Hot 100 singles chart, which included the meme-driven ascent of Rae Sremmurd and Gucci Mane’s “Black Beatles” and Migos’s “Bad and Boujee,” the lengthy conquest of “Despacito,” and the breakout success of Cardi B’s “Bodak Yellow (Money Moves),” which even Taylor Swift couldn’t halt. The current No. 1 on the Hot 100, Post Malone and 21 Savage’s “Rockstar” is a unique case, too: a cut of the song appears on YouTube that features the song’s hook looped over and over again, and plays of this version of the track count toward its streaming totals.

On this week’s Popcast, Mr. Caramanica discusses the text and subtext of the Billboard Hot 100, and how the rule changes might punish certain audiences and genres, with Joe Coscarelli, pop music reporter for The New York Times, and David Turner, senior staff writer at Track Record.
