Cave Story - Balcony:
Donkey Kong 2 - Thorn Thorn:
Donkey Kong Country - Aquatic Ambience:
Teehee Valley from Mario and Luigi Superstar Saga
And Kanto Gym/Trainer/Wild battles is up there as well
Definitely NieR: Automata. It gives me chills whenever I listen to it.
The game itself is an absolute masterpiece in every aspect, not just the OST
