Heh, there was article on HN a while back explaining that in order to be truly creative, you have to first master your domain.
So I wonder if this new information will allow master composers and musicians to gain a deeper insight into their craft and then achieve creative advances they might not otherwise have. I've recently gotten into trance, dubstep, and their many, continually emerging sub-genres, hence my interest.
As for me, I'd be happy to just be able to make stuff I could post to Newgrounds or Youtube and get decent ratings. Though now that you mention it, I wouldn't turn up my nose at #1 pop hit-generating startup either.
