BTS is a seven-member South Korean band , who write, compose and produce their own music, with a variety of music genres (a lot of hip-hop in their early days, then pop, rock, and some classical (Lie), jazz, R&B (Singularity), or korean traditional music (Ddaeng) arreglements), and this is a very important thing: they sing about current social themes, which some media outlets and fans have attributed for their success.
Their music isn't english, but it's in their mother tongue and it's so deep, so human. Their melody and lyrics transcend regional borders, language, culture, and institutions.
So, please, value good art, regardless of country, race or language!
