My favorite music with a melancholy note

I have a few favorite instrumental pieces from various dramas that bring me into a strange state of suspension. Whenever I listen to them on my playlist, I freeze. No matter what I do at the moment, this music makes me stop and listen carefully to the end. While listening to them, I remember emotions and reflections that I experienced while watching specific scenes in these dramas.
