Someone asked this on Reddit, and I thought my answer could make a fun thread. Here’s 4 smaller Korean artists with a similar sound and aesthetic to NewJeans. Especially if you crave more songs like Ditto, Super Shy, Right Now and NewJeans (the song):
Hanhee - 902+1
iiso - Salad Days
iiya - New!
Bebe Yana - Strawberry Kisses
