Hierarchical indexing of tags with multiple values?

From what the OP said about not wanting to see classical subgrenres when looking for rock, I suspect it is the latter. In this case, the tag update file should contain

@GENRE=Chamber
-GENRE=Chamber
+SUBGENRE=Chamber
etc.

Of course. Thanks for the clarification.
