A movie or film score is the background music of a film (which is generally categorically separated from songs used within a film). The term soundtrack may be confused with film score. A soundtrack, however, contains everything audible in the film including sound effects and dialogue. Soundtrack albums may also include songs featured in the film as well as previously released music by other artists. A score is written specifically to accompany a film, by the original film's composer(s). Read more on Last.fm.
