Unless there's a massive public outcry I'm going to politely ignore your argument (for now) -- not because it's a bad one -- I totally get it -- but I think there's a much better way of fixing this. Just fix the friggin metadata. As part of the mega update we're working on we'll be rolling out the ability to auto correct your tags (just as we fetch missing artwork). This seems to solve the problem you have AND (and this is the important part) it takes out the administrative chore of organizing your stuff manually by folders.
