This annoys the hell out of me too, especially because I like the more aggressive and noisy side of classical music. I don't of course want it to be that all the time, but I need at least some kind of intense climax in a classical composition. If something is just called "relaxing" I usually don't waste my time with it. I usually like to think symphonies as some kind of heroic journey, as an adventure, and I'm not big fan of classical music that has little sense of struggle and drama (baroque and the actual classical-period classical).
