South Korean boy band BTS makes a big splash in the top 10, as the seven-member group's new album, Love Yourself: Her, debuts at No. 7 with 31,000 units (18,000 in traditional album sales, just less than 4,000 in TEA and a little under 10,000 in SEA).
BTS earns both the highest-charting album ever on the Billboard 200 by a K-pop act, and the genre's biggest sales week. The group beats its own record, as the act's 2016 album, Wings, was previously both the highest-charting K-pop album (debut and peak at No. 26 on the Oct. 29, 2016-dated list) and owner of the biggest sales week for a K-pop title (11,000 copies sold in its debut frame -- all from digital albums). Notably, Wings and Love Yourself: Her are the only K-pop albums that have charted in the top 40.
