Oh Brother Where Art Thou is a good one.

Tron 2. Daft Punk without lyrics is perfect for me.

Trainspotting
Hackers
Atomic Blonde
Go
Grease
The Big Lebowski

Mary Poppins

Koyaanisqatsi
Solaris (the remake)
Whiplash
Broken Flowers
The Fountain
Pirates ot Caribbean

• Conan The Barbarian by Basil Polidouris
• Aliens by James Horner
• The Good The Bad And The Ugly by Ennio Morricone

Either Pulp Fiction or Judgment Night.

A few of my favs, in no particular order:

• The Lord of the Rings trilogy
• Tron: Legacy
• Oblivion
• Gladiator
• Star Wars (especially Episode I)
• Interestellar

Haven’t seen anyone mention Cinema Paradiso or The Good the Bad and the Ugly. Both are wildly different. Ennio Morricone is a genius.

There’s also The Incredibles - Michael Giacchino The Greatest Showman - Various Artists
Saving Private Ryan - John Williams
The Prince of Egypt - Hans Zimmer
The Gospel of John - Jeff Dann (great middle eastern vibe)

Guardians of the Galaxy 1 and Footloose are probably my favorites of all time. It's really hard to find soundtracks with a better collection of absolutely amazing songs imo.

My favorite is the soundtrack to Princess Mononoke, composed by Joe Hisaishi.

Clerks

Dune (1984)

The Fifth Element

Lock stock and two smoking barrels, and o’ brother where art thou, and tron (daft punk)

Tron Legacy

The Crow

Shrek 2

Sucker Punch

Amélie

The crow

Escape from New York.

Oldboy.

Spider-Man: Into the Spiderverse

Not a movie but all 3 Beastars openings sound so good

A few that spring to mind...

Vertigo
Psycho
Twin Peaks: Fire Walk With Me
Mulholland Drive
All 3 LOTR films
Star Wars OT
Indiana Jones (especially Raiders)
The Sweet Smell of Success

Already lots of LOTR & Tron: Legacy here. Not seeing much love for animated film scores, so on that note & in no particular order:

• How to Train Your Dragon trilogy, 1 is personal favorite
• Kung Fu Panda trilogy, 2 is ~~so fucking good oh my god~~ personal favorite
• The Lion King (1994)
• Spirited Away
• My Neighbor Totoro
• Spirit: Stallion of the Cimarron
• The Super Mario Movie
• Finding Nemo
• Up

A couple of these have great soundtracks, too, but I do love a good score.

• Cosmos
• Blade Runner

Vangelis, enough said.

• Blade Runner - Vangelis
• Miracle Mile - Tangerine Dream
• That Thing You Do! - Tom Hanks, Adam Schlesinger, others

Star Trek 2009 (Michael Giacchino)
The Mask Of Zorro (James Horner)

Scream 3

Django unchained

American pie

Spiderman into the spider verse

Kill Bill Volume 2! And I like the Carol (2015) soundtrack (totally not a lesbian).

Fight Club.

So many good ones, I don't know how to choose.

Soundtrack or score?

Soundtrack: Judgement Night. Paired hip hop artists with rock and metal bands. Biohazard and Onyx fucking tear it up. And Faith No More and Boo Yaa Tribe sounds incredible.

Score: Terminator 2. James Cameron is incredible about quality sound in his films. One of the best directors for sound in the biz.
