To get the song from the trailer...

Since this question has been repeatedly posted here, I'll make this thread for all of us to share our various methods.

I was looking for a way to download that haunting music from the trailer but couldn't find any links. I couldn't even find out the name of the song but here is a way I used to get an mp3 of the trailer music.

1) Find a trailer on Youtube with minimal voice-over interruptions.
For example: http://www.youtube.com/watch?v=iirGjM3T5QI

2) Find a site that converts a video link into an mp3:
For example: http://www.listentoyoutube.com

3) Enter the video address listed above (or whichever video link you've chosen) and then the site will create an mp3 file of that video.
