Oooohhh it's so chill! Me likes. It has a nostalgic feel to it.
After a number of listens (I lost count XD) somehow it still holds my interest. The song adds some interesting contrast to the art. Where the art has a more depressing tone, the song kind of brings a sense of bittersweet denouement. It really puts the listener in the art subject's shoes. Watching one's memories flash and scatter like the sun rays above them.
