definitely interesting.
as with any sort of academic survey though, everything hinges on definition. (what does "more independent" actually mean on a practical level? what does "emotional qualities of music" actually mean? etc.)
the definitions of working terms always determine how true to life the hypothesis is. that's what makes science a bit sticky. but it also makes it even more validating when a reliable pattern is discovered. i'd be interested in reading more of that study to see what the conditions were.
