It's a great song for a melancholic mood while not being outright depressing in itself. In fact, I'd say that the song builds up to a sense of triumphant grandeur that helps build its own story through the music. It reminds me of traversing through a time with a sense of nostalgia and loneliness before emerging to find something greater that brings a sense of comfort while still being awe inspiring and humiliating at the same time.
