Hmmm i'll give you some of my personal faves instead of the most popular or something
This last one is a remix that Suga made but i recommend listening to the songs separately too they are really good
Ignore that most of these are from a playlist that's my giant 800 song playlist
These are just a few
As for the member run down:
Namjoon (RM) - The fearless and 200 IQ leader (no srsly that's his IQ (i'm not kiding (really))), an awesome rapper, has the cutest dimples and smile, had the worst hair ever in their debut days. Also my bias. He wrote and produced a lot of their songs too
Suga - The second rapper of the group, raps hella fast (seeing as you liked Ddaeng listening to his solo... you'd probably love it it's called Agust D). looks really bored and dead half the time, acts like it too, but can be squishy and loves his members very much, also writes and produces a lot
J-Hope - The third rapper, isn't as experienced as the other two but... he's learned a lot, is a great dancer, sunshine of the group, endlessly smiling and being positive, he's your hope, your his hope, he's J-Dope.
Jin - The visual of the group, loves calling himself worldwide handsome, makes the best (worst) dad jokes ever, has a really funny laugh, get's picked on even by the youngest, isn't the best dancer or singer but he tries and can really outshine the others sometimes tbh
Jimin -
@Jimin you do this i wouldn't give my bias wrecker enough of an introduction
Jungkook - The main vocal, squishy and hot at the same time, Harry Styles of BTS (lol), voice of an angel, is savage af and a bit annoying at times, still love him tho, also the maknae
V - The face of the group and handsomest man on earth, is basically a visual, unlike the other vocalists is a baritone and has a really unique husky voice that he sometimes has to overuse for their songs. Is quite the allarounder, the purest being on this planet, literal saint, i can't even with him... he's such a good boy i literally can't idk how he isn't my bias tbh. Loves gucci. Is also a giant dork
