Impossible to chose just one. Many dramas had one or two, or twelve pieces I liked, so I'll present just a sample.
1. Gaho - Start. Because it's energetic. And because it's Gaho.
Giriboy - Hyena. The whole OST deserves to be here, frankly.
Chanyeol & Punch - Go Away Go Away. I am stil slightly obsessed with it.
Nafla - My Friend
Kang Seung-yun - Can You Hear Me
SAAY - Happiness
The Rose - Strangers
O.WHEN - No Regret
Hong Isak - Close Your Eyes
Jun & Chan - Where You Are
Woosung - You Make Me Back
Elaine - Fallin'
Jeong Yeop - Doors of Time
Poetic Narrator - Who I Strolled With
Yi Seung-yeol - Till The End
Hye Lim - It's Gone (Chip In, 2020)
Doko - Psycho
Jeebanoff - It's Too Hard For Me
And of course countless instrumental scores from lot of dramas (like Search, but couldn't find it).
