For a while, Mozart’s Piano Concerto No. 21 was known as “the theme song from Elvira Madigan”.
Are you fucking kidding me? 42 posts before somebody mentions Heavy Metal? 
I love the soundtrack from Requiem for a Dream, but I know the movie itself is also quite powerful. That one song though … I keep hearing it in other movies, like I think LOTR used it.
Pump Up the Volume was a forgettable movie but a very good soundtrack.
Evita ?
Almost all of Mark Knopfler’s soundtracks. I love Local Hero, but have only seen it a couple of times. The soundtrack? Listened to it a couple hundred. But some of the films are pretty obscure:
Local Hero (1983)
Cal (1984)
Comfort and Joy (1984)
The Princess Bride (1987)
Last Exit to Brooklyn (1989)
Wag the Dog (1998)
Metroland (1999)
A Shot at Glory (2002)
Altamira (2016)
2001
Flash Gordon
Bolding mine.
You’re kidding about The Princess Bride, right? That has to be one of my favorite films of all-time.
Folks, I give you The Lemon Drop Kid. Raise your hand high if you’ve watched it. Uh uh. Thought so.
Ever heard of a Christmas song called “Silver Bells” though?
I loves me some concert films! Stop Making Sense - Talking Heads
Under a Cherry Moon was basically a movie of the Prince album Parade
A fairly mainstream movie with Leo DiCaprio and Clair Danes, Romeo + Juliet did okay and seemed pretty well received, but that soundtrack blew me away! YMMV, of course
I remember a lot about the movie. But not the soundtrack at all.
(I was an original subscriber. Den! Had like the first year or two of issues. Lost in a move. :()
Paris Blues has a fantastic Duke Ellington soundtrack. Despite a fantastic cast, it’s a dull mass of cliches and only worth watching for historic reasons.
The movie FM put out a double album of contemporary songs to complement the radio theme. Led by Steely Dan’s hit single of the same name, it was far more successful than the movie and went platinum.
Mine too. Come to think of it, half of what I say is quotes from the movie. That’s why I said “But some of the films are pretty obscure.”
There was a version of the main theme called “Requiem for a Tower” that was used for the relevant LOTR film trailer.
A string quartet named Escala who got noticed on Britain’s Got Talent covered that version as the lead track on their debut album (which is one of the last physical CDs I ever was gifted/bought).
Singles and Empire Records are basically my teen years. Honestly. I owned almost every outfit. Yes, the soundtracks were amazing, but so were the movies.
I agree with Pump up the Volume, but um…everyone forgot The Legend of Billie Jean? Pat Benatar’s Invicible deserved SO much better!
See post #5.
Setting aside, for a moment, the fact that “The Imperial March” is actually from The Empire Strikes Back, you seriously believe that Star Wars is mostly known for its soundtrack?
Star Wars spent a year in some theaters. I suspect it was know for EVERYTHING.
Let’s go back a few years:
Lieutenant Kijé is an obscure 1934 Soviet comedy (!), largely forgotten except by the most diligent students of 1930’s European cinema. However, the film’s original score is one of composer Sergei Prokofiev’s most well-known and respected works:
The Lieutenant Kije Suite. Thisis probably the most well-known part.
Across the Universe is a very excellent movie. Shame on anyone who hasn’t watched it! 
The soundtrack includes 33 different Beatles songs, all sung by the movies’ actors themselves. (Some weren’t professional singers but still do a splendid job.) The storyline is an excellent romance story, but was designed in part to allow scenes to be punctuated with appropriate Beatles lyrics.
As just one example, here’s a minor character in the story, telling us of her lesbian love. This character is named Prudence. (Guess which song is directed at her character when’s she’s pining over another unrequited love?)
