KJ103, in Oklahoma City, is sampling "DNA." Programmer JJ Ryan chats about championing the K-pop song, BTS' first Hot 100 hit.

Welcome to the Billboard Chart Beat Podcast, where each week co-hosts Gary Trust and Trevor Anderson, from the Billboard charts department, discuss why what's on the charts … is on the charts, while also looking at current chart action in a historical context for even greater insights.

With BTS making history on the Billboard 200 this week – scoring the first top 10 ever for a K-pop act, as its album Love Yourself: Her debuts at No. 7 – it's time for a quick, emergency, BTS-only podcast!

Concurrent with the group's album debut, BTS makes its first Billboard Hot 100 appearance, as "DNA" debuts at No. 85, powered by 5.3 million first-week U.S. streams and 14,000 downloads sold, according to Nielsen Music. The third component of the Hot 100 – radio airplay – is almost entirely lacking, however, although one station is leading the way on the song: iHeartMedia's KJYO (KJ103) Oklahoma City, Oklahoma. It's the only station that contributes to on Billboard's Pop Songs chart (among more than 150 reporters) that played "DNA" more than two times in the week ending Sept. 24, spinning it eight times, including in morning and afternoon drive.

Says KJYO programmer director JJ Ryan, who joins the podcast to chat about the song's airplay on the station, "The foundation [of top 40] is, 'play the hits and play them often.' But, in between all of those songs, you want to sprinkle in new stuff. And, you want to play new stuff that's reacting, whether it's selling, or has a ton of social reaction. Hands down on this one, the decision was social media. Reaction was so big, it felt weird to play it one time and not play it again.

"So, we're playing it a little bit, at least one or two times a day, to let our mass audience get to know the song."
