positive addition of sound

one film in particular that i think of in which sound was added in a positive way is Punch Drunk Love. throughout the entire film there are transitional shots of morphing color with sound that accompanies them to set an almost eerie but peaceful mood. The music of the film fits the overall mood of the film very well I think too. While much of the movie is kind of shocking and somewhat disturbing. they keep the overall calm and happy feeling of the film with the music and then change it up when you see bits of color. Some of the other music of the film, comes from an organ that Adam Sandler's character finds by his shop. The resulting "music" or tones that come from this organ seem to go along with with the his characters personality. Very timid and demure but when messed with can become very harsh and surprising. I think that overall the creators did a great job in deciding the tone of the film and getting and creating sounds that would go along with that mood.
