Anything handled by Nobou Uematsu.

How has nobody mentioned Rimworld? Such an incredible soundtrack!

Aquaria: Original Soundtrack by Alec Holowka

Such an underrated game. RIP Alec.

I'll skip the obvious ones with multiple artists like Furi, Katana Zero, Hotline Miami, Crypt of the Necrodancer...

Journey

Witcher 3: Lelelelele

Hollow Knight, though I don't really listen to it outside the game.
Cyberpunk has some great songs on the radio.

Katamari Damacy!

Assassin's Creed 4: Black Flag is a close 2nd Edit: almost forgot about FEZ!

Chrono Trigger

A lot of great choices already: Persona 5, Hades, Katamari Damacy.

A kind of odd left-field one I'd like to add specifically for great music in-game, is Guacamelee 2. I don't know that it's the kind of music I'm likely to put on just to listen to randomly, but as far as in-game atmospheric music goes I think it's both tremendous and refreshingly unique amongst the landscape of video game music.

Ace Combat, all of them but especially the PS2 Holy Trinity.

Shadow of the Colossus.

NFSU2, Most Wanted and Burnout 3, even if theyre licensed music and not really original.

Doom midis in general are fun. Touhou games too.

Final Fantasy VI, so much so that when OverClocked Remix kick started a remix album, I donated to it

Metroid Prime

• Metal Gear Solid 4: Guns of the Patriots
• Far Cry 3: Blood Dragon

Pokemon USUM. If there was a looped version of the tracks, I‘d probably listen to it every day lol, it just boosts my mood. Sadly, the soundtrack (that I have) has them at 1-2 minutes.

Bloodborne OST is the first that comes to mind for me.

Prince of Persia 2008

Outer Wilds (and Echoes of the Eye) technically qualifies with the community's rules, but I think the answer more in keeping with the spirit of things is Shadow of the Colossus. The Opened Way is the most "fighting a building-sized monster as a normal guy but still winning" piece of music I have heard

Undertale, Celeste, Katamari, Syonara Wild Hearts, Shadow of the Colossus, Metal Gear Solid, Persona 4G, Persona 5R

Feeling nostalgic and I was just listening to the Pokemon gen2 soundtrack

Gravity rush is pretty damn good. Haven't played the second one yet

The Last of Us 1 & 2, all the Katamari games, Death Stranding

Civ 3 had some killer modern music.

Trepang2

mantis Lords from hollow knight

Ash of the Gods and Pilgrims

Dance Dance Revolution Extreme 2, OBVIOUSLY.

Hyper Light Drifter and Return of the Obra Dinn for different reasons.
