I used to love (still do!) the soundtrack from About a Boy- Badly Drawn Boy did the entire thing and it's brilliant

Officially updating mine to a 5-way split. Don't ask me to choose between them.

Louis & Bebe Barron - Forbidden Planet (1956, first issued 1976)
Eduard Artemiev - Solaris (1972)
Philip Glass - Koyaanisqatsi (1983)
Vangelis - Blade Runner Esper 5CD 25th Anniversary 'Retirement' Edition (2007)
William Basinski - Disintegration Loops 9xLP + 5xCD + DVD + Box Set, Remastered (2012)

Either Forrest Gump or Pulp Fiction.

My top five favorite movies are my favorite partially because of the soundtracks.

Aliens, The Prince of Egypt, Anastasia, The Fifth Element, Forrest Gump. There's also The Dark Crystal, Aladdin, The Lion King, The Godfather.

Definitely Forrest Gump.

One of the best has gotta be the Blues Brothers movie soundtracks for me - but not for those particular recordings, but to prompt me to dig out the old originals of the songs they do. Some great choice of numbers in those movies.

Better still - Good Morning Vietnam, which has all the original songs, but as a Brit I'm not really into the story.

Best Movie soundtrack of all time - the one from the film PIRATE RADIO (The Boat that Rocked)
Just sheer magic, every single track. The film is a great story, though it was slated because its not historically correct, but the music just brings it alive. Great vibes.

Easy Rider.

Steppenwolf, Smith (covering The Weight), The Byrds, Hendrix, Fraternity of Man, mondo chill.

The Silence of the Lambs score was what made me even consider listening to film scores. It's gorgeous. Then Psycho is, of course, a classic and for good reason.

I also really like Pet Sematary, which is strange because it's quite dissonant, I've never seen the movie, and it's a ripoff of The Amityville Horror.

Gorgeous.
