I really like the “Flower Boy Next Door” OST that Park Shin Hye sang.
Yes many may say that it’s not that much of a song, and she doesn’t have that much of a voice. But I still love the song, especially the accoustic version. It makes me really calm and serene somehow.
If anybody’s wondering:
Pitch Black - Park Shin Hye
Just search it up on Youtube.
One I like most is one that few people know - “Windstruck”. Might be hard to find subbed, but as of a few weeks ago it was still up on YouTube. Features YouMe and some American soundtracks.
It’s too old… I love !!! it’s making me nostalgic. relish ! xD
Gosh I love this song, really emotional and sensual… and “Heartless city” is one of my favourite drama ever and have definitely one of the best OST.
