Because of my childhood:
Clocktown from Majora's Mask, with ambient background noise that follows the three day cycle and changes on a loop.
and the Song of Storms set to Rainy Mood.
I don’t really listen to much video game music, but the FTL: Faster Than Light songs [i]Space Cruise (Title)[/i] and [i]Milkyway (Explore)[/i] are super relaxing.
I listen to whatever is on my mind. Hollow knight, halo, destiny, death's gambit, dead cells, dark souls, and warframe occasionally. All of them have really good soundtracks that in some ways inspire different parts of my formless story arc I'm working on.
