You don't really need special support for this. Most music players have a mode for shuffling albums at a time, not individual tracks. Just make a classical playlist and select that mode. As for shuffling your entire library, I don't understand why you'd want to do that. I get in the mood for certain genres; I don't want to jump from Rainbow to nordloef to Massive Attack randomly over the course of 10 minutes.
