well I created some view schemes as sort of "dynamic" smart playlists:
for example, with items as "rating", "genre" and "number plays", with just some clicks you can have all your 3 to 5 stars classical tracks or all rock tracks played more than once, and so on ad lib.
as far as filtering directions I think the theory is this (I hope I remember corrrectly what happens...):
Rating Genre
------------------
** Classical
*** Rock
**** Pop
Filtering in one direction (left to right):
- if you select only the ** rating and in your DB you have only Classical and Rock tracks rated **, than the Pop entry disappears
- whatever you select in the Genre item doesn't modify what's shown under Rating, even if the selected item's, e.g. Pop, tracks have two stars or no stars at all
Filtering in both directions (left to right AND right to left):
- if you select only the ** rating and in your DB you have only Classical and Rock tracks rated **, than the Pop entry disappears
- whatever you select in the Genre item DOES modify what's shown in Rating, so if the selected item's, e.g. Pop, tracks have two stars the "***" and "****" entries disappear.
Hope it's clear (and also real...
