It's really late here, I just finished my assignment and now I'm bored so...
Let me start (I stan BTS)
EXO: Their vocals are insane, probably the best I've heard among kpop groups. Forever is one of my most fav kpop songs ever.
BLACKPINK: Extremely charismatic, all 4 members are the "main characters". Rose has one of the best vocal tones in kpop.
TWICE: Extremely hardworking, very kind and humble. What is love is a great song.
BIGBANG: Till recently, I was one of those few people who thought BB were extremely overrated and then I came across a compilation of their stage performances and I was shook. Now I understand why there are legends and every idol in existence is their fan.
TXT: best discography PERIODT. I stream anti-romantic religiously, I won't be surprised if it emerges as my most played song on spotify this year.
STRAY KIDS: Probably the next big thing and hella deserving. I always appreciate self producing idols and bang chan(?) is a really cool.
ITZY: Best dancers in kpop currently and I'm a simp for ryujin.
ENHYPEN: great performers and likable personalities. Their popularity internationally is no joke, I have a feeling that they are going to be hugeee in the future.
NCT: A diverse group with bunch of talented men, also vocally superior. Idk much about the members but their main center is such an eye catching performer.
AESPA: very new to them but next level is addictive, I'm glad it's doing well. Also probably the next it group in korea.
TREASURE: talented, best in variety among 4th gen.
ATEEZ: their stage presence is no joke and I really admire them for that.
DAY6: I didn't know they existed until I joined this forum but their music is great. I discovered them thanks to that one user that always spams their songs.
These are probably all the kpop groups I've listened to ( mayble I missed one or two )
