Korean Music Recommendations - Non-idols (Part 2)

Been 8 months since my last music recommendations post! I keep wanting to do an idol version but I'm just so busy (and lazy) all the time.

I'm on a 1 week break now, after which it'll be 3.5 months before my finals. Sounds like a long time but it's actually really near.
I haven't been watching much dramas either because I had an OSCE (Objective Structured Clinical Examination) test in January, and then Chinese New Year celebrations in February and an Anatomy Spot Test just recently. It's been a very busy couple of weeks. And I've been hooked on Produce 101 lol! Started watching for Kahi, but it's really quite entertaining and addictive. Will do a post on it when it ends in April.

Variety: Chicken Surfers/Shut Up and Surf

Chicken Surfers is about 6 Korean "celebrities" who go to Bali for surfing, but the caveat is that they are only given 100 chickens, which they must use to exchange for whatever they need (mainly food and surfboard rentals) in those 7 days.
The Korean name is dalk chi go surfing (닭치고 서핑), where dalk chi go = shut up but dalk = chicken.

The 6 people are - Park Joon-hyung from legendary boy group g.o.d, Kahi the ex-leader of After School, Lee Su-geun the comedian, Hyun Woo the actor, Maeng Ki-yong the chef and Ye Jung-hwa who is a.... fitness instructor (?) who joined in episode 3. I have no idea who she is hence I put the celebrities in inverted commas.
