Koreans love Arirang, a folk song that’s over 600 years old and deeply rooted in their culture. It’s more than that, though, because Arirang is the sound of strength, longing, and the winding road home. So when BTS chooses to name their long-awaited album “Arirang,” it’s clear the present isn’t the era of “Dynamite” glitter but one of the souls behind the suit. BTS did the same thing: they took a break to “compost,” letting everything break down so they could come back even stronger. With Arirang, BTS destigmatizes the idea that “traditional” is “outdated,” setting a new precedent that they can be the biggest group in the world while remaining very Korean.
