music

I believe they added external music to the movie because people like to relate music with everything. In today's world, people have been able to relate to music in many ways because music gives us something to hold onto. There are so many different varieties that it can satisfies human feelings and emotions. People as well as the artists themselves have found music to be therapeutic whether in the melody or in the lyrics. 

The movie satisfies our sense of sight, rather, but the music draws us into the picture; into the movements. Music brings an emotional character that captures our attention and keeps the motion alive. Watching a motion picture without music seems so blah, plain, boring. Music gives it life, music makes movies. If you have an incredibly good directed film and the music simply does not fit, the movie will not be good because no one will understand what the director is trying to portray. Music is what gives it meaning, helps us express excitement, fear, loneliness, happiness and success. Music makes the world go round, it is a universal way of expression found in all cultures and found in almost all movies for viewers to react to.
