What is your favourite video game soundtrack?

[Kedjane]

What!? Need you ask?
Shadow of the Colossus has the best video game soundtrack of all time - there can not possibly be any discussion about it. It's simply amazing and I can't even imagine how lame and unexciting the game would be without it.
I've never even thought of any other soundtracks because I know Shadow of the Colossus is the king of that hill. I've listened to several other soundtracks such as the Metal Gear Solid series, Devil May Cry 4, Silent Hill, Penumbra, Mirror's Edge and so on. The Starcraft soundtrack is pretty good but nothing comes close to Shadow of the Colossus.
