BTS, also known as the Bangtan Boys, is a seven-member South Korean boy
band that began formation in 2010 and debuted in 2013 under Big Hit
Entertainment.[4] The septet—composed of Jin, Suga, J-Hope, RM, Jimin,
V, and Jungkook—co-writes and co-produces much of their own output.
Originally a hip hop group, their musical style has evolved to include a
wide range of genres. Their lyrics, often focused on personal and social
commentary, touch on the themes of mental health, troubles of school-age
youth and coming-of-age, loss, the journey towards loving oneself, and
individualism.
