How not to use a soundtrack!

This episode has a serious problem, the dubious choice of soundtrack placed in the middle of the choreographed martial arts scene. Note that the moment character X says something and the soundtrack sound is louder than it should, also note that it is not wrong to put soundtrack while a conflict occurs, or any scene, but it must be done well, I will give three dramas that serve as an example: Ever Night, Sword Snow Stride or Joy of Life.
There are other points to be mentioned, but this for me was the most serious.
