I've tried to enlarge upon Most accurate programs to find similar music?. Please advise of further improvements or reopen?
With your editing it, the question was automatically placed in our review queue (see my comment on it due to that). I'm personally still a bit concerned about the "most accurate" part, as that would require somebody to "know them all" – but apart from that, it's already specific enough to "be valid" IMHO.
Asking for further improvements which could be made: An example of the expected workflow might be helpful, but I'm not sure if it's really necessary.
