I have soundtracks, or original soundtrack scores, by composer. First and foremost, there is John Williams, followed by Alfred Newman, and then Bernard Herrmann. I like Danny Elfman, Howard Shore, Jerry Goldsmith, John Barry, Maurice Jarre, Bruce Broughton, Elmer Bernstein, and Dave Grusin. They comprise the core of the bulk of my collection. Alfred Newman is probably the greatest film conductor of all. Williams has perhaps the greatest number of original themes. Goldsmith and Barry have a wide variety of scores. Elfman, of course with his gothic scores, especially Batman and Spiderman. Broughton's score for "Silverado" is perhaps the greatest western score ever written next to Berstein's "The Magnificent Seven". There are many sites online devoted to film music. I have them all in my browser if you want some really good links. Let me know.
