the OST (not a plot spoiler)

Someone has posted the soundtrack on youtube. It's very eerie and there's a snippet of something we have heard before. It's great listening to the music and imagining what the visuals are going to be. I can't imagine why people go to the spoiler board. I'm almost not wanting to know about the space jockeys! My imagination did a fantastic job without a movie for the last 20 odd years.
