spent ages coming up with the perfect tagging system for all classical works (not as simple as people might think haha!), as well as file naming and folder organization, etc., so that sorting and searching would be natural and easy for what I wanted (you have to take into account various systems and the way they sort numerically and alphabetically with files and so on, it wasn't logical numeric order, so leading zeros were required--thanks Microsoft haha!).
I agree about tagging issues with classical, and would add that jazz, with its fluid mix of artists, bands and combos also presents issues for me in organization.
This comment inspired me to start a new thread on the subject of organizing and editing folders, filenames and metatdata.
