Also includes soloists!
Pentagon (my ult group, ofc<3 Honestly, whatever genre you're into, they probably have dabbled in it. You will most likely find a song you enjoy!)
The Rose (They are a soft rock/alt band like Day6, only less popular. While I do love Day6, I actually find The Roses' music better.)
#GUN (He participated in the survival show No Mercy, and is very close with Monsta X's Joohoney.)
3YE (A three-member GG, my favior song of theirs is OOMM.O
D.Holic (to some extent)
Brave Girls (Rollin'. That is all I have to say.)
Kard (The most popular co-ed group, and perhaps the only one--- At least that I am aware of.)
Kyungri (former member of 9muses)
Bang Yongguk (of former B.A.P. Goodness gracious, go listen to his music. It is amazing.)
Stellar (They were amazing before Marionette. They switched to a sexy concept because they were not doing well. Not their company's fault either, they were probably in debt.)
Hinapia (Their debut song, Drip, is my favorite!)
Anda (Check our her song "What You Waiting For"! Yes, this came out before Somi's. Her most popular song is probably Touch.)
and here are the groups that I like but not a stan of necessarily that are underrated:
E’Last, golden child, limelight, class:y, infinite, nature, Apink, tripleS, OnlyOneOf, tempest, purple kiss, omega x, epex, CIX, p1harmony
