Seems the game's music is in the .raw files in the "streams" folder. Since they're raw samples, without headers, they can be copied together to one file in batches, which can then be opened in Audacity as 44100Hz 16-bit stereo audio (though some of the voice clips in there seem to only be 22050Hz). I took the time to puzzle together all the music for you people.

Have fun with it!

Oh, since the .raw files contained an instrumental version of the Last Pint theme, I also cobbled together a clean version of that without Roman talking over the start.
