#12 awake
From Inkipedia, the Splatoon wiki
This song from assorted stages in Splatoon 2's octo expansion has a ethreal, dreamlike sound to it, making it sound distant. it's heavenly vibe is calmly accentuated be several different beat changes and it loops until silently ending off on a fading note.
Note: i cannot put the song here because i do not have legal permission to do so
