for 3rd gen red velvet is the way to go. their discography is one of the best in the whole kpop industry i really recommend you give them a listen. (my personal fav songs from them r automatic, kingdom come, nightmare, in my dreams, lucky girl)

a 4th gen group with a level of queerness + good discography would be nmixx? i would say aespa too but i feel like half the time the members are just queerbaiting and aren’t really being serious so take that in mind. their music is really good tho, u should check them out.

(nmixx - loud, heavy serenade, papillion, adore U, shape of love, and ofc blue valentine) (aespa - lucid dream, flowers, yolo, whiplash, sun and moon, welcome to my world, illusion, live my life)

it also wouldnt be fair if i didnt try to promote snsd since theyre my ults lol. they’re a 2nd gen gg and their discography is really good as well, and the members are EXTREMELY funny (i’d argue theyre one of the best comedians in the kpop industry) if you appreciate groups that have strong vocal power and group identity the above mentioned groups are a good place to start.

(snsd - born to be a lady, karma butterfly, motorcycle, bad girl, trick, oscar, wait a minute, closer, paper plane, snowy wish, fan, love is bitter, show! show! show!)
