Some of these were already mentioned but nevertheless, amazing music is present in many great games!
Final Fantasy IX, Hollow Knight, Final Fantasy XIV, Witcher 3, Outer Wilds, The Talos Principle, Disco Elysium..
But my absolute favourite soundtrack from a game is one that I love even more than the game itself (which is absolutely fantastic, too!).
NieR: Automata - the music is just otherworldly. It fits the game but even when I am just listening to the soundtrack by itself it just makes me feel things. An absolute masterpiece.
