SONG HAS BEEN FOUND! Space Song by Beach House the song was identified by Beach House, confirmed by the songwriter of the song Victoria Legrand. After 8 years of searching the song has been found.
(theoretically this vid is posted at a point in the timeline where bravely had not yet been found. Months down the line we can pretend it's been identified in a similar fashion to bravely)
