I concluded that more soundtracks feature it than were listed but more subtly or something. There's no way I haven't heard that before and I've never seen the Orchestra, except for the St. Paul Symphony Orchestra in the late '90s, and I was pretty sure I wouldn't remember it from that.
Doesn't really have to do with music, but this is a lot like the experience I had a few years ago when I was trying to figure out how I remembered the actor Michael Pare from the Eighties. When I looked up his filmography and TV-ography, I was certain I'd never seen anything listed--but I clearly remembered him from the Eighties. I've never figured out where I knew him from.
