I'm not quite sure about how to code music boxes and the like, but it would be interesting if there would be music boxes with far-eastern music for adding more to dynasty builds, as well as maybe other things, such as various other town musics so that each town could have a bit different air around it. (I love the new "town" and "town night" tracks too, of course, but how cool it would be, if some towns would have different music. - well, that can be done with music boxes, of course, and there are tons of tracks, but there aren't really track for example for a far-eastern town or such... how about a quiet snowy town? or an exotic jungle town? or a desert town with a hustling and bustling bazaar? or...?
I think such could be very interesting.
