There is one song on my playlists that I can literally put on repeat and listen to forever. I have yet to grow tired of it. There's just something about it that's so moving and epic. Hans Zimmer is a really great composer, he's written a whole host of amazing movie scores: The Lion King, Gladiator, The Dark Knight, Sherlock Holmes... Inception's entire soundtrack is really great, but this song, its final track, is really worth a listen (on full volume, the beginning is super quiet).
