I personally would have put Howard Shore’s “Fellowship” at the top rather than the bottom, followed by Vangelis’ “Blade Runner” and Williams “Star Wars” stuff. And if I were to pick a Jerry Goldsmith work, I would have chosen “Rudy” instead – but that is just my “Notre Dame as my alma mater” bias showing (considering I was on campus for my senior year while they were filming the movie). Of course, Goldsmith’s “Rudy” work gets played at times other than showings of the movie itself, including various other movie trailers, and the Olympics broadcasts. So it can’t be all that bad, really…

Other than that, this is a great list – well done!

Seeing as I’m a big fan of Clint Mansell’s soundtracks, I’ll point out some of his other works. The ensemble soundtrack (I really like the distinction in terms) for PI is an excellent primer into electronic music.
Mansell’s soundtrack for ‘Requiem for a Dream’ included the Kronos Quartet, and a theme called ‘Lux Aeterna’ that’s been remixed into so many different formats (seen in a symphonic version in the trailer for the Two Towers, for one). Haunting violin stuff.
And of course there’s The Fountain. One of my favorite scores ever, I think. Surging symphonic chords, somber piano moments, emotional swells.

Koyaanisquatsi does indeed exist, though it was very rare and hard to find until only a few years ago when it was re-released on DVD. Before that it existed mostly on carefully-guarded VHS, which is how I saw it back in college.

Related to that, with another good soundtrack, is the movie Baraka. It was shot and directed by Ron Fricke, who was the head cinematographer on Koyaanisquatsi, and is in a similar style (music and visuals, no narration or plot), but considerably more uplifting in places (i.e. it doesn’t end on an exploding rocket). Highly recommended to see at least once in a lifetime.

Constantine: Great for its weirdly compelling atmosphere.

Dark City: Dynamic and Dark.
