I like that approach, although if we want it to be extensible, we'll 
have to declare the /org/mpris/MediaPlayer2/TrackList/ space off-limits 
for media player use, except as prescribed by the standard.

In fact, it might be worth explicitly stating that media player 
implementations should use either paths outside of /org/mpris or an 
explicitly "allowed" space (say /org/mpris/MediaPlayer2/TrackList/Tracks/).

I think this is a sensible approach anyway, so shall we go with that?
