Okay, I re-read it. First of all, a very important distinction. The article says most influential soundtracks, not scores, like the thread lists. So by this standard, I'm more than a little surprised that West Side Story or Sound of Music (both of which won slews of Oscars and had songs you still hear today) aren't on there. While the film/songs are based on a play - pre-existing material - the same would apply to 2001 or American Graffiti.
Also, when did the Golden Age Era end? Nick thinks we're still in it. Bryla thinks it ended in 1950. A friend of mine insists it ended with the 60's (Viet Nam, hippies, Color TV, R-rated movies, etc.)
Someone needs to come up with a list of the most influential scores in film history where scores such as Jaws, or one of many choices from Goldsmith would certainly belong. Or of the "Golden Age Era", assuming it ended in 1959 (???), and include scores like Citizen Kane, Casablanca, The Third Man, etc.
