I was playing the Stardew Valley OST at work this week. That’s music to get shit done at a relaxing pace.

Zelda botw. Lots of piano mixes on youtube

Uplink is a game about hacking that’s got fantastic tracker music for it’s soundtrack. Blue Valley is just great background music, no strong melodies, just chords and vibes.

FEZ has a great soundtrack. Also Sword & Sworcery.

Paradox games are pretty good (Stellaris particularly)

Portal/Portal 2 aswell

Solar 2 is also a personal fav but hard to find OST other than on YT

Doom or doom eternal.

FTL? Into the Breach? Diablo II, Cities Skylines, SimCity 3000, The Sims.

60 minutes of N64 chill tracks on yt

Honorable mention: Soma.fm

soma.fm not game music but the amount of vibes they offer means that one of those vibes will likely fit your study music needs :) and commercial free.

Tunic has an excellent soundtrack that’s one of my favorites for work music. https://invidious.reallyaweso.me/watch?v=nnvjKf_mRYM

The Cyberpunk OST goes crazy, and the Risk Of Rain franchise has some killer stuff.

Stray has a great soundtrack

Stellaris is quite good for that

Crono Cross, anything from monster hunter Tri and up.

Something I’ve been using during work these days is Maplestory bgm playlists. Reminds me of my youth, and jav a very calming effect on me :)

Anything from Supergiant Games

I just make a point to remove the songs with lyrics because lyrics distract me.

I use Wh40k: Mechanicus & Ixion
