Strange Things Happen audiobook - music

[lancaster]

Wow! I've been listening to the first cd today, after having read the book a while ago. I'm enjoying this enormously!
Stewart's reading makes the stories stand out in a way than just reading the book didn't. Great idea. A lot of work for HIM, but a great idea for US!
Anyway, I haven't heard a lot of the music bits between the different chapters before. On the cover it reads that it's all his own music. But there are no liner notes, and I was wondering of someone knows about the different pieces. They're extremely varied and go with the stories so well that some of them seem to have been especially composed for the audiobook, but I have absolutely no idea of this.
Any input?

Thanks!
