According to Audiotuts, the number one, the greatest, the most magnificent soundtrack is A Hard Day's Night, by The Beatles.
I may be committing blasphemy here, but having not grown up around parentals who listened to The Beatles, I just don't think they're that great. I've seen A Hard Day's Night, and it's about as good as Spice World or one of those Elvis films (and I love Elvis, so to pan his films is a big deal).
There are a few soundtracks on their list I agree with, however. Trainspotting is an incredible film with an incredible soundtrack. Grease has an iconic soundtrack and O Brother, Where Art Thou's music suited the film perfectly (this remains my favourite Coen brothers' films of all time, don't even get me started about the nothingness that is Burn After Reading).
In fact, I've noticed some regrettable omissions on the list (which admittedly is subjective, anyway).
Sci-fi adventure Virtuosity's soundtrack is a brilliant compilation album, and the mad electronic-industrial grunge was ideal. I can't forget Traci Lords's song 'Fallen Angel', and this film introduced me to the industrial techno gods that are KMFDM. And we also got to see Russell Crowe's bum, the first time of many.
Hackers is a film I've mentioned before. I've seen it so many times I can tell you what part of the movie we'd be watching just by listening to any song on the soundtrack. All the greats of dance are on this soundtrack - The Prodigy, Orbital, Underworld, Stereo MCs... (perhaps I'm showing my age).
The classical arrangements and Sting number '(In The) Moonlight' on the film Sabrina are so moving I almost chose that CD for my wedding. It may not have been the greatest remake of all time, but the music!
Plus Harrison Ford and Sting are two rather cool old dudes.
Going retro now - I only saw The Commitments once but I've listened to the soundtrack countless times. What's not to like about a bunch of Irish people singing old school rock music? If they were playing concerts, I'd be first in line to buy a ticket.
And finally, who can not like the raunchy numbers in The Full Monty? The film was perfect escapism for a couple of hours, it showcased some great acting (and not so great bodies), and I'd dance with Hugo Speer or Robert Carlyle any day.
