Sky Chase Zone - Sonic the Hedgehog 2

Salt Tank - Dreams

No drum and bass in the Jazz room

Or

Gregory and the Hawk - For the Best

Faith’s Hymn by Beautiful Chorus. It’s a capella, very gentle and harmonious humming and singing. Spotify

Currently Sleep Token - Euclid, if not the entire Take Me Back To Eden album

Pikmin music can be so relaxing

Lemon Jelly - Ramblin' Man (the whole album is good, but Ramblin' Man is very chill)

Mr. Scruff - Keep it Unreal (I especially enjoy Midnight Feast, Shanty Town, Jusjus and Fish.)

I started listening to Slayer - Raining Blood while shaving as a joke, now I‘ve conditioned my body to focus when this song plays

Devin Townsend - Deep peace

Sabotage - beastie boys

There isn't a single one.

But, I'd have to give the nod to either "fade to black", Metallica; or "closer to fine", the Indigo Girls

Fade to Black should be obvious. It's the lyrics, the feel of the song, etc.

Closer to fine isn't really about the actual lyrics, it's about the sentiment of them, of moving through life and reaching new places and becoming. You get closer to fine by whatever path you're on. So, when shit is real, it's nice to have the reminder.

Follow the Sun - Xavier Rudd

Not necessarily a song but Fred Rogers's voice is pretty damn soothing
