Electronic music has proven itself in today's films, and is an impressive tool if used properly. With the computer technology of the present, even computer games can have, and are beginning to demand, professional music scores. Film scores' are no longer confined to films, and this allows more composers to enter the industry and to advance it. It would appear that contemporary film makers are afraid of silence. There has to be dialogue, action, thematic music, or at least atmospheric music to prevent silent portions of the film.
Atmospheric music can have themes, but is confined to the background at a low volume.
This may work well for the film but is not very 'listenable' on a soundtrack CD without the movie visuals. Rather, composer Williams continuously reworked the themes so that the music was always identifiable. Though unintentionally, he created a score that is closer to classical music and tells a story. Atmospheric music works for the film, but it shouldn't be released as audio alone. This seemed to be a significant change for many, and it certainly attracted crowds to Disney movies.
