1, these background music or soundtracks are really beautiful.
2. Music can infect and express emotions. These examples you cited are all TV soundtracks. Through these soundtracks, you feel the joys and sorrows of the characters in the play, as well as the ups and downs and impermanence of the plot, which should be regarded as causing * * *.
3. The style of these soundtracks may be your favorite type, so you will pay special attention. This is nothing, because your personality, including your mood and experience at all stages, will change your favorite music. It's like occasionally hearing a fast song, although it's not the kind you usually listen to, but when you are in a good mood, you will hum a piece of music or twist it with the beat, similar to this situation.
My humble opinion, it doesn't matter.
