Wings
I could see their dying noteIn the sky that is so oldI remember where they once flewWhere they sang to the morning dewNow their wings are soaked in oilCaged wings that can't unfurlNo longer do we hear them singNo longer do we hear the flutteringOf wingsUnderneath the iron birdTheir song cannot be heardAbove the human soundAbove the poisoned ground From Letras Mania
