We could make ly:music-property accept stream events as parameters,
but give warnings.

Hm.. it's a bit problematic that certain events (NoteEvent) will be
split up into one Music and one Stream-event. Perhaps we can construct
a hack that handles invalid music-property settings by checking for a
Stream_event child and try to set it there instead, along with a big
fat warning.
