Great, great idea because most of the time you don’t have any feedback from buyers and you have to look at most popular tracks to feel the direction. Even those who already bought item from you never tells why. First of all this point can help to author open his skills in some success kind of genre and create couple of variations, and second is he don’t need to copy anyone cause he will know whats the value he has.
So, any solution which can help authors and customers to find link, will be really useful.
