Are eBook Soundtracks the next big thing?
Booktrack thinks it is (Daily Finance).
I have posted links to songs that inspired me when I was writing a story, but that is a very different thing than an auto generated playlist that tracks my reading speed. I don't think I would like this at all.
I am not sure how many people will like to have music timed to their reading. If they do some kind of Music Genome Project and let Authors tag portions of the book by mood so the music is appropriate, it might work, but other than that, I cannot see it.
What do you all think?
