I recently started playing GTAV again and sometimes I’ll get in my car and let the radio stations play while I do house stuff. Favorite stations are the 80s one with Kenny Loggins, and West Coast Classics and Rock Radio.
Castlevania (series, special mention for Symphony of the Night)
Chrono Trigger/Cross
Dead Cells
Destiny 1/2
Dragon's Dogma (mainly Into Free, but still...)
Final Fantasy (series, but special mention for XI and XIV)
Persona 4/5
Portal 1/2
River City Girls (probably 2 as well, but still waiting on my LRG copy)
Scott Pilgrim vs the World (the game (the soundtrack))
Tony Hawk (series); a bit of a cop out, as they're all licensed songs
Zelda (series, special mention for the Cadence of Hyrule soundtrack)
And then just a lot of old nostalgia for NES games (Duck Tales, River City Ransom, TMNT, etc) and SNES/PS1 RPGs (Lufia, Super Mario RPG, Suikoden, Thousand Arms, etc)
But that main list contains the ones I either bought or downloaded because I loved the music so much.
Just like the other commenter, the Outer Wilds main motif (travelers) makes me emotional because of how good the game was. Disco Elysium also has had an amazing soundtrack, with the main BGM faintly using sounds from the final song, which made it really cathartic for me.
Ultrakill deserves a lot of praise, especially for the P-2 music (https://youtu.be/MG5L-1pI8bI). It works perfectly for how intense the level is, and it's absolutely nuts that the game still manages to up the ante after you've perfected every single other level. I've listened to this type of music quite often before, but I've never felt it in my blood and muscles before playing that level.
When judged on the music alone though, Hotline Miami (1) and Furi have to take the cake. Both soundtracks are just iconic, and easily stand out on their own.
not to be a hater but GTAV Radio station songs are 'licensed music' not soundtracks, also you can just fire up spotify or youtube if you just wanna listen to them instead of running GTAV each time
Vampire The Masquerade Bloodlines
Deus Ex
Hotline Miami
Unreal Tournament
Journey
Cyberpunk 2077
The Witcher
Jet Set Radio
All the Silent Hill (even Downpour)
Colony Wars
Final Fantasy VII and Chrono Cross are my absolute all time favorites. Ori and the Blind Forest is a more recent soundtrack that blew me away. The soundtrack for the Motorhead racing game is also a classic for me.
Honestly I'm shocked and surprised the Risk of Rain soundtrack hasn't come up. Both 1 and 2 are bangers. Chris Christodoulou (the lead composer) has a yt breaking down the soundtrack.
Stellaris' ost is also up there for memorable leitmotifs and just plain understanding the assignment.
I'm surprised not to see any of the Monster Hunter games yet! Maybe that's because most MH soundtracks are more a collection of individual themes than a unified soundtrack for a world, but a lot of those tracks are pretty great.
I don't know whether it is considered polite to link to youtube recordings of tracks here. My particular favorites from World are all zone themes: "Rulers of the Wildspire", "Dancer in the Coral Highlands", "Roars across the Hinterlands". You hear these tunes a lot - whenever you're fighting something in that zone that doesn't have its own theme - so they'd better be good. Fortunately almost all of them live up to that standard!
Quite a few folks have mentioned Outer Wilds, so I'll add the DLC soundtrack. The titular song (Echoes of the Eye) that plays at the end of the DLC makes me burst into tears every time I hear it. But in a good way, haha.
Having finally finished Horizon Forbidden West last night, I've got to choose that. Instant favourite for me. Nostalgic moments when the theme kicked in in one of its altered versions, and the credits just completely floored me. Stuck around for the whole 30+ mins. Wonderful.
Away from that, Mass Effect always needs a mention!
The 7th Guest and The 11th Hour remain top-tier for me. The music was half the experience, turn it up and just enjoy that creepy vibe while solving puzzles. And they're all on The Fat Man's Bandcamp now!
Ace Combat, mainly Ace Combat 5 but all of them are well known for their soundtracks.
More recently WARNO has excellent music so far, even though most of it was licensed by Eugen from third parties so it doesn't really count as a soundtrack specific to the game.
I have played 4 Warhammer games and never touched the tabletop. Don't know how I got into this game but once I did, it didn't leave my head. I have one shuffle list I listen to and this sits there very comfortably.
Recently I completed Crossing Souls. It's a game overloaded with 80s nostalgia. The soundtrack is from two composers. The first has 80s synth tracks while the other providers John Williams / Amblin like scores as the story of a group of young friends and feels like a movie from that time.
Assuming visual novels count as "games", probably one of the best soundtracks I've ever run across is the one for EverlastingSummer. Both Silent Owl (Sergey Eybog) and Between August and December did amazing work on it.
My favorite would probably be Super Mario Galaxy 2 OST. That game had really good music, so good I think it got nominated for an award or something. The music is nice and riveting.
Super Mario Galaxy (1+2). Orchestrated music should be a must for main Nintendo games at this point, outside of Zelda (and the Pokémon anime, although that one's not strictly Nintendo or used in actual games, sadly).
Every time when people talk about game soundtracks, they should include Chrono Cross
For recent games, FFXVI has an amazing soundtrack, I think the OST will be released on July 19th
I recently replayed Persona PSP, and that game has amazing soundtrack, but kinda marred by the fact that there's only one non-boss battle them, and the encounter rate is too high, so you ended up listening to the same song all the time.
Shadowrun for SNES had a pretty fantastic soundtrack. It did a lot with very little and really paints a picture of the setting very quickly. Another candidate from the same era is Planescape: Torment. It had this great haunting ambient sound that made Sigil feel so strange and ancient.
At the time though, if you'd asked me which game had the best soundtrack, I've had pointed to Tony Hawk, though I'm not sure if it was 1 or 2. The one with Party at Ground Zero. Found some great music of the era that way!

In no particular order:
Final Fantasy XIV and XVI (Soken is a genius)
Transistor
Nier Automata
Genshin Impact
Destiny 2
The World Ends With You
Persona 5
Tony Hawk Pro Skater 1/2
Honestly though the FF series as a whole kinda deserves its own special mention. The games have always had stellar soundtracks.
