Hans Zimmer again shows how he is the bets at what he does, again and again we get magic movie themes from this master -- superb ending to a good film, and the first time i heard this tune while watching the movie, is truly a 'hair rising on the back of neck' moment.
I can only recommend searching for other good tracks Hans has done, such as The Rock, Gladiator, Pearl Harbour, and Last Samurai.
I love this bit of music from the film, but I did not want to buy the whole soundtrack. Amazon allows me to downloaded just my favourite bit of the music to my i-pod, paying for just the bit I want. Brilliant!
