I notice the tag filter does not work very well because it forces you to account for all tags. This kills the results when any individual tag is missing even if the title of the song is fairly close.
There are situations where it is much better if you ask for a 100% artist or album match and then a fuzzy title match. You could still average your tags criteria into 1 single % rating as you obviously aren't going to make 3 extra result columns.
