I like the story, but all the "music talk", especially in this chapter, is writen by someone that doesn't know what they're talking about, only buzz words and blurbs from KPop PR teams.
I'd like to know what irl songs, if any, they had in mind when describing the one in the story, so I could hear what they mean by "heavy and gloomy blues" played with only a violin, that turns into "upbeat hip hop" with guitar and drum (but no bass?!), then another "genre" and mood, all the while keeping the same melody.
