Note 1: Dan suggests a form like PlayTune $CurrentSelection$
Note 2: For multiple scripts that wish to speak different messages, or for a single script that wishes to select from a group of 
messages, must be able to specify tune ids separately (conveniently).  Furthermore, this requires some hooks for voice rope 
reference counting that aren't already present.
