Unless there is some way I'm not thinking of...
Basically what I'm trying to do is create a search screen that searches all of the mp3 tags album/artist/genre/etc, without having to choose which one you want. Then in the filter results box you would see the results and what tag they match...
The best way to describe it is from this screenshot I took inside windows MCE
Here I just did a search for Gar which finds song titles and artists and albums that match the search... but without the tag to the right of each, its not clear which filter it matched with..
With the new advanced searching allowing multiple filters this could be really nice.
