My first thought was KOYAANISQATSI by Philip Glass (because it's so uplifting and hypnotic, and one of my very favorite scores) - but I doubt it would appeal to such a wide audience. Therefore I'll say Bernard Herrmann's NORTH BY NORTHWEST - another of my "personal best".
A movie few have seen because it is a documentary and not yet on DVD. It has not one, not two or three, but FOUR main themes, one more beautiful than the next. It is in my top 3 scores of all time. RIP Maestro Barry.
The last thing I want to witness (or even know the results of) is a group of people listening to master crasftsmanship from a person or persons who have honed their skill over many years and took the time to write music with depth and orchestral colors that dazzle the mind, only to find some douchbags playing with their phones while it's playing, people not listening, some commenting "It doesn't have any lyrics", and others asking to "Turn that shit off".
It's a nice movie scene to have some people all loving what you put on, but unless it's a group of preteens and those up to 29 and you're playing the latest hip hop or rap crap that makes you think your brain will die right then and there, don't even try it.
On a side tangent on songs...
1960's, 1970's, even if I didn't like the song that was on, I could still tolerate it.
1980's: same thing.
1990's: it was getting harder and harder as each year passed.
2000's: Almost impossible to hear a song that was good. I'd have better luck playing Pick-Up Sticks with my buttcheeks.
Current: I can't even accidently tune in to any channel that isn't an oldies; I have my radio channels in my car pre-programed to avoid all other radio. When I hear songs coming from other people's cars, it's such utter (often mindless) garbage, I often have to roll my windows up and play something even if I wasn't wanting to hear anything.

This happened to me. I was at a party with other people in their late 30's a few years ago and the host was explaining what Spotify was. He let us each take a turn picking something to play to the room. Everybody picked some crap song that they all LOVED. I, of course, played a piece of pretty film music (I forget what) and they all just bitched and moaned the whole time it was on. Not a fun experience.
For sheer beauty, I would share with the world Barry's ROBIN AND MARIAN. I don't think a lot of people in the world know that score. Perhaps a more familiar one I'd share because it is so beautiful would be Horner's LEGENDS OF THE FALL. Both scores are too beautiful to go unnoticed by people who don't collect film scores.
Either Blade Runner Blues (the New American Orchestra cut) or the end titles to David Newman's Paradise.
Truth be told though, I don't often subject others to my tastes in music (because I suppose mine are niche) so there are some more "pop" songs I'd play instead. This lovely song comes to mind: Chris Bell's "You and Your Sister".
This is gonna sound nutty, but something of the Goldsmith / Dante projects, like Explorers or Innerspace, because they express this marvelous optimism and childlike sweetness and awe at the universe.
Wondering what I might choose, and looking at others' choices I couldn't agree more than this one. Wonderful choice that shows both the beautiful and more action oriented of Morricone's best scores.
Pressing on I might think of:
Vertigo Bernard Herrmann Jason and the Argonauts Bernard Herrmann The last two Dollars scores Morricone, plus many others inc Fistful of Dynamite Star Trek TMP Jerry Goldsmith Star Trek II James Horner
