No. The only way to detect when a song is about to be played is a call
to playableUrl() (I can't remember whether it is used in other places
in lieu of a prettyUrl() method (I can't even remember if we have a
method like that). If you do not want to or cannot do the downloading
of the file in playableUrl(), you might have to add an
aboutToBePlayed() method to Meta::Track which would be called a few
seconds before we need the file.
