The song was written for/about the hobbit film, i think, cuz it's the closing credits of the desolation of smaug, and of course, Durin being one of the seven dwarven kings. I think it describes the destruction of the town under Smaug's mountain, hence all the references to fire, desolation and blood, etc.
