This thread is quickly going to become Silent HIll: The Thread, but here's my pick
Alone in Town - Silent Hill 2
I listen to this song constantly. It's one of the few songs that stays on my "life soundtrack" playlist. I love it so much.
Crystal Teardrops - Symphony of the Night
This is another one I listen to all the time, and stays in rotation.
Honestly, you could take these two songs and extrapolate my whole taste in music from them. They're almost like proto-vaporwave, BGM that doesn't necessarily feel like traditional BGM. It's so atmospheric that I feel like it creates a place more than just a tune. It's basically the reason why I love stuff like
Haircuts for Men.
