Samurai Shodown series has an amazing soundtrack. A mix of traditional Japnese sound, rock music, chaotic jazz, and ambient sound that barely resembles a song. The ending of 3 is my ultimate 'get pumped' song:

Tony Hawk was a big one. The EA sports games always have some bangers that get stuck in your head. One of my favorite video game moments, though, was bombing the tobacco fields to Bomba Estereo's "Fuego", in Far Cry 6. They employed music well, throughout, but that moment was really enveloping.

Star control 2 was the absolute best imo

Underwater theme from donkey Kong country

Your reality is amazing

Modern Warfare 2 (2009)

Left 4 Dead

Warcraft classic - TBC - WOTLK - Cataclysm

Castlevania, Zelda and Silent Hill (though I'd say all first 3) mentioned so I'm gonna say Alundra. Sure it's very Zelda/JRPG, but that game had some amazing music that just sticks with you.

Also a little tongue in cheek, but Adventures of Lolo. I'm not sure if there's just one song throughout the trilogy, but it sure feels like it. Weirdly it doesn't bother you. It's like a hypnosis that just makes you play one more level. One more try. Kind of like the Tetris soundtrack, but it never gets old.

Skyrim was pretty epic… even the “wandering around” music was perfect.

But my #1 is Still Alive (closing theme song to Portal).

I'm going to give honorable mention to Buck Bumble on the N64.

I remember basically nothing about the game, or even if it was any good, but I rented it once at blockbuster and like 2 decades later the theme song still pops into my head once in a while.

Hughe fan of the low roar songs in death stranding

Shadowrun for Sega Genesis

Unorthodox opinion here but Wasteland 3, the first time the Battle Hymn of the Republic played over a fight was incredible.

A few i havent seen mentioned.

Sonic 2 and 3 on megadrive. Especially the ice zone with the snowboard on 3. https://youtu.be/hYxlqTpZ-24

Icewind dale. The kuldahar music is epic. https://youtu.be/B92P1-OUNJo or easthaven in peace https://youtu.be/ERd5stTsaBc

It’s not better than Tetris I’ll admit. But I’ve always had a soft spot for the Mass Effect soundtrack.

Really really obscure but I could never take this song off my head, from A Thousand Arms, psx game. Game was a goor jrpg.

Kenshi has some of the best ambient music. Scorching wind gives chills every time.

Tunic has an otherworldly soundtrack. It's perfect music to listen to while working. https://youtu.be/nnvjKf_mRYM

I'd say Sayonara Wild Hearts. It's a rhythm game so expertly crafted with the musicsoundtrack it gives me chills. It's so, so good

For me personally some of my favorites (most memorable) are:

Hitman 2: Silent Assassin main title (and first half of the OST)

Divinity Original Sin 2 main title

Original vanilla WoW main title music

Sanctuary from Borderland 3’s OST

BFG Division from DOOM

Pretty much the entire Skyrim soundtrack

Most of the Witcher 3 soundtrack. My favorite is probably On the Champs-Désolés, which is from the Blood and Wine expansion.

For me definitively the soundtrack of Boneworks (which is also the best VR game I know). Especially its main theme ("Bone Theme") and "Who am I"

Some more awesome OSTs in no particular order: Minecraft, Banjo-Kazooie / Banjo Tooie, Witcher 3, Risk of Rain 2

Wingspan. I have the Vinyl OST.

Monument Valley is quite nice too.

I'm going to go for a bit of a deeper cut and say Mad Rat Dead. They took a genre which relies so heavily on the strength of its music (rhythm platformer), and produced a soundtrack where literally every song is a banger, and produced some great emotional moments as well--the transition from Cottage House to Kind of Hope and Neuchatel still makes me choke up just thinking about it.

I'm a big fan of the Offworld Trading Company OST.

The theme song of Locoroco. Though the lyrics are in a made-up language, I can feel the desire for world peace in this song.
