It's a dramatic track commonly used in movie trailers. Requiem for a Dream, also by Clint Mansell, is a less dramatic version (and the original) of this track.
A relection on the cycle of drudge associated with being poor and ordinary .Its musical setting is not a million miles away from a post beatles McCartney,great chorus and strings back up this plaintive non sentimantal ballad.
