I bought the Soundtrack on iTunes and it is really great. The coolest thing is, the monologues of the machine and of Mandus from the games ending are included. Also the music used in the trailer.
And if the machines final monolouge doesn't give you the biggest chills ever you can't be human imho.
I wrote Ms. Curry an "thank you" email (adress is on her homepage) and she replied and was very happy that so many people liked the score. You all should do the same, let's get the lady some more credit, without this score it wouldn't be half as scary and atmospheric.
