Well, I know I'd do it personally, as azuarc said, for initial sorting. Of course, if I'm being totally serious, I'd probably have a fairly-close-to-normal-distribution entirely by accident. Which, would have the side effect of likely having half the songs at 5 or under. I don't even try to do it intentionally, it just seems to happen.
Personally I don't mind either way, but your call.
