First, the music in the movie is part of the movie.

In action movies: coordination of actions, the combination of strength and beauty.

In comedy films: profound scene themes attract the audience into the play.

In romance movies: the emotions of the characters are more obvious.

Second, the music in the movie makes people's impression of the movie more profound

Modern movies often draw on ready-made music, such as "The Guinea Pig Team" I just watched Coincidentally, the song "boom boom pow" by the Black Eyed Peas is also used in another American action movie I just watched (the title has not been verified yet).

Third, the concert will become even more outstanding due to the success of the movie

I personally think that in the past movies, the music was often tailor-made, and the songs would become popular because of the movie, such as the Yugoslav movie "The Bridge" "Goodbye, Friend", the theme song "Red Dust" from Sanmao's script "Red Dust", Anita Mui's "Rouge Button", and songs famous for movies such as "Casablanca" and "Farewell My Concubine". From this it can be said that movies have influenced music.
