Ian Eisendrath, the executive music producer of the surprise Netflix hit — which has been gaining steam on real-world music charts — breaks down how the songs came together.

The 'KPop Demon Hunters' soundtrack debuts atop Billboard's Soundtracks chart and in the top 10 on the overall Billboard 200.

To date, only three other K-pop tracks have reached No. 1 on the same U.S. chart: "Seven" by BTS member Jungkook, "Who" by fellow BTS member Jimin and "APT." by Blackpink's Rose. Among K-pop groups, BTS had held the highest ranking on the chart at No.
