Audio-Bibliophiles discussion

Hi all, any thoughts on Booktrack.com - which has taken the idea of synchronising music, effects and ambient tracks to text and made it a worldwide phenomenon. My personal connection to this is the love of music and writing and wish to prompt more discussion on the merits of the combination. One example of my own making and still in development can be found at outinvention.wordpress.com/2017/09/06... - this will give you an idea of what I am talking about. I think it is important I gain user feedback from audiobook listeners/ebook readers to see how music and text could best be combined. My first thought is short fiction...any thoughts?
