I was recently linked to a site that randomly selects a song. The song that is played becomes the theme song for your life! Here it is: http://vip.aersia.net/vip.swf
When I clicked on it I heard Dissidia: Final Fantasy - Messenger. It's a beautiful track, and pretty apt. I tried it again a couple of times, and it turns out that they have a pretty decent collection! Try it out and see if what you get fits. Feel free to share what you got!
