Update: Pick your Soundscape to Match the book

I made an update to set a soundscape per book. This change was made that the music might not fit the book and now you don't have to switch the soundscape everytime. It helps build the atmosphere. Not all book have the soundscape options and if have want a book to have one, let me know.
