Some of the music from the demo has been updated since (Bram Town Theme for example), and others will receive updates at some point in time, but I'm not really at a point in development where I want to stop forward momentum to go back and touch that stuff up just yet. Some of the tracks are lighthearted, others are a little more sinister- there's a track player in the demo (in the options) if you want to check out some of the themes from later in the game as well.
