If you still don’t know anything about BTS, you sure as hell do now. (And also, we made a helpful guide for you!) The ridiculously successful Korean boy band made history this week, as they’ve officially become the first K-pop band to net a number-one spot on the Billboard 200 chart with their new album, Love Yourself: Tear. The seven-piece group have been making waves in America as of late due to some strategically chosen awards-show appearances, which was reflected in the 135,000 albums sold in its debut week. Billboard notes that the feat is particularly remarkable due to Live Yourself: Tear being mostly performed in the Korean language, as well as the band’s previous album, Love Yourself: Her, only getting to the seventh spot on the chart last year. A hearty congrats to them, they seem like nice boys.
