Odd. Apparently, we're expected to be skipping tracks more than listening to them.

Yeah, and that's why I want this manual rating / weighted shuffle functionality so much

Ditto. I'd LOVE to have this since i listen in full shuffle most of the time and end up skipping a majority of the songs. This would really be a valuable addition to the player funtionality IMHO. I'd use the hell out of it.
