I am haunted by the beautifulness of this song. Of course I've tried Shazam and squeezing my brain but to no end. It's in this compilation and only 5 second of it available to listen. I've pasted the exact time of the video in which the song plays. https://www.youtube.com/watch?v=YcgMH2Y0rvw&feature=youtu.be&t=258
