I do not know what like sound aesthetics you're going for but here's who I've been listening to: Red Velvet Le Ssserafim Mamamoo (+solos) XG Bibi (has a great collab with Yoonmirae!) ILLIT (will check out their new stuff) and I've heard some stuff from H1-Key I liked (they're newer)

I don’t have a broad range / spectrum when it comes to GG. I’ve only been listening to KATSEYE so far and in the past, 👖.
