A RhythmDBPropertyModel groups the entries in a RhythmDBQueryModel by the value of a property. For example, a RhythmDBPropertyModel using the RHYTHMDB_PROP_ARTIST property can be used as the model for a GtkTreeView that will list the artists present in the query model.
The album/artist/genre browsers displayed in the library and other sources are populated using a RhythmDBPropertyModel for each property.
