Calm music tracks from retro PC games recommendations?

"Not" Donkey Kong Country:

Waterworld's OST is pretty calming an I use it from time to time while working.

This song, and this moment at the start of Pokemon Mystery Dungeon - Explorers of Sky. Oh man. Changed my brain chemistry ngl. Just so freaking beautiful, so quiet, so weirdly poignant for a Pokemon game, definitely lots of nostalgia playing into my feelings but damn. It's a very calming song. Feels like the end of a chapter, beginning of a new adventure. Damn it I gotta play Explorers of Sky again haha.

I think the car theme from Fallout 2 fits that bill perfectly

Not all of these are exactly what everyone would call "retro" but here's a few tracks from old PC MMOs. That genre is a treasure trove of calming music

Old Cabal Online had some nice tunes.

Detonator has a very good OST in general, but this song in particular is very calm:

It reminds me of Hotel Dusk

How about some Contact OST?

Someone in the comments said Power Cell is similar to this one from Neon White:

Sorry I couldn't find PC games soundtracks for sleeping, hope you still like these though.

Most of the tracks from Yume Miru Kusuri. I never finished any of the routes because the situations are too exaggerated for my liking, and the VN makes me extremely sleepy with its soundtrack and dreamy artwork.
The game turns 20 years old this year, so maybe it can already be considered retro.

'Dolphin' from The Longest Journey is a chill trip-hop song that you could listen to in the afternoon or evening.

A few years ago I found comfort in the Ecco soundtracks. They helped me get through a bad time, and sometimes I'd fall asleep to the music.
