(pls listen to 3D, Seven, Yes or No!
English:Greetings.I recommend you to listen to Aespa, Ive, Soojin, Le sserafim, (G)I-dle.These are k-pop groups/Solo artists who are quite popular, but they have cool songs.
hm... lately, i've been listening to a lot of kara, u-kiss, and stray kids! also a lot of older k-pop like click-b, dbsk, and nrg! outside of k-pop, i really like grouper (sorta chill, ambient music if you're into that).
dynamicduo, dpr ian(i dont think he's in kpop anymore because he releases a lot of english albums as of recently),kai and deantrbl if you like rnb.
if you prefer experimental genres, check out shinee, f(X), exo and infinite (or literally any 2nd gen groups)
but also, check out the ogs who brought kpop worldwide. bigbang, t-ara, 2ne1, snsd, btob, wonder girls and litereally any groups from early 2nd gen.
but some 4th gen groups are great too like cix, cravity, treasure
