Classical music is used constantly in background of movies.
However, whenever a character is seen playing or enjoying classical music, it’s time for them to commit an atrocity (usually Nazi).
It's late and there is so much to say but I'll just follow up on your post.
In my humble opinion, good, if not great orchestral music is entering a golden age due to the ability of just about anybody who has the desire to make orchestral music to have access to the necessary tools available to them via the PC. I myself have whole sampled orchestras at my disposal along with the ability to write musical scores that these samplers can play as well as a very capable multitrack digital recording studio. In the past a small percentage of musicians were able to take advantage of such a wealth of technologies and many took the path of popular music from the jazz age to big band to the rock era. All these genres were relatively diversely represented.
Classical music, on the other hand requires a massive investment of time and effort to become proficient enough to play as a professional and the job openings are minuscule compared to other genres. My favorite musical genres include Vocaloid, ProgRock, FolkRock, Opera Metal/Orchestral Metal, EDM/Dubstep/Chillstep, Experimental Electronic, Polka, Hot Jazz from the early 1900’s to about 1940, and Big Band from the 30’s and 40’s, along with Classical.
I have created a number of experimental electronic pieces that are the sonic equivalent of abstract visual art. It's relatively easy with the right gear and maybe 1 in 100 people who hear it actually appreciate it. I've also done a handful or orchestral pieces and the effort needed to come up with something even just halfway decent is at least an order of magnitude greater, however, even I can make music that sounds nice and if I were to devote a much greater portion of my time I could do much more. Many civilians do.
What I have seen over the last decade or so is classical music becoming orchestral music, a musical form using traditional instruments in pieces that depart from traditional structure, short pieces that typically run from four to ten or so minutes long as well as film music. In fact I think you will find that yesterday's great composers have become today's film soundtrack composers, John Williams and Hans Zimmer amongst others. Google Epic Orchestral music and you will find a wealth of talent on Youtube.
One last point. Out of all the examples I've cited I do not know not do I care what race the musician who made the music belonged to. If it's good music I'll listen to it, if it's bad music I won't, but I'm sure somebody else will. I'm also sure that The Cleveland Orchestra will never perform RapCrap no matter how much A.A whining comes their way.
