My favorite composers are James Horner, Hans Zimmer, Randy Newman, Alan Menken, John Williams, Elmer Bernstein, John Barry, Philip Glass and Jerry Goldsmith, and several other musical giants of Hollywood who have, time & again, proved that a great original score can lift a movie by several notches, and, in case of of a promising movie material, the score simply translates the scenes into pure magic.
Alas, I couldn't include all the great compositions of the masters in this very listing. But, this I can assure that the ones I've named are close to my heart. Each album generates a deep personal association, with the movie, and the tracks.
The names in the list aren't in any order, chronological or preferential.
