10 K-Drama OSTs Sung By K-pop Idols Every Fan Should Add to Their Playlist

While we agree that Korean dramas are always exciting, the OSTs can totally make or break a moment. A slow, emotional tune is enough to bring us on the verge of tears, while the peppy ones have us dancing right alongside the characters. And those OSTs featuring K-pop idols only from K-pop groups? It’s truly the best of both worlds.

So, here are 10 K-Drama soundtracks every fan should add to their playlist:

1. Boyfriend By TXT's Yeonjun :

This song is like a gentle breeze on a warm summer evening, the kind that wraps around you like a soft hug. Yeonjun usually known for his raspy and rapping style voice, surprises us with his tender and soothing vocals, pulling at our heartstrings and capturing the excitement and uncertainty of young love. It also fits in flawlessly with Cinderella at 2 AM, as the drama deals with themes of second-chance and fluffy love story.

3. Blue Flower By ITZY's Lia:

While K-pop idols don’t release osts that often, ‘Blue Flower’ marks the ITZY main vocalist’s second time contributing to a kdrama Alchemy of Souls: Light and Shadow’s soundtrack. “So I’m standing with you / Bearing a blade / Deep in my heart / That can’t be pulled out / Still I’m praying for you / With this painful wound / That can’t be cut down / I’ll embrace you,” croons Lia in the chorus. The song is highly emotional and focuses on love that is unconditional and transcends life and death.
