I suggest you hook in a completely different place. Tracks from what collection 
do you want to watch? If it is SqlCollection, I suggest you hook in 
SqlTrack::setRating(). For tracks not in any collection there is 
MetaFile::Track.

If you need to watch tracks from various collections, you could become their 
observer by implementing Meta::Observer, but that would be inefficient to watch 
entire collections etc. Also, some tracks are not file-based (MTP collection), 
some could be remote..
