I'd like to reboot this search, but to approach it from a different angle. I suggest employing a sort of "music genome" technique similar to what Pandora does for their music suggestions, identifying the unique sounds and features for each section of the OST. For those of you who have listened to the OST, you will have no doubt noticed that each song is split into multiple, distinct sections, almost as if each section was it's own song. Another aspect to note is that (in my experience) the 'Superintendent Shuffle' hardly ever plays the sections from the same song. If we can come up with an easy way of identifying each section, this project will become so much easier, and players won't just be saying "The music changed in Squidhenge," they will be saying "The music changed from the second section of Deference for Darkness to the first section of The Menagerie!"
