Found this video courtesy of a PC world newsletter(shout-out)and loved it. You'll find yourself watching it over and over again. This is literally one guy with a love for all things John Williams and a lot of time on his hands. He just sat down and recorded all 4 parts separately and then mashed them all together. Even if you don't like John Williams or Star Wars, you still can appreciate this creative mash of movie soundtracks and adapting them to one theme.

Here's the link to the page if you want to see how to download the song:
