Thanks for the quick reply, Conor.
Gotcha. All that makes sense. The 'Sort Artist' solution won't work, unfortunately.
Here's the basic gist:
The CDs on my shelves are organized by artist. But, in the case of Various Artists/Compilations/etc, they're sorted by title. In CDPedia, I've organized them accordingly in the 'Location' field (by copying the artist column, then adjusting the 'various' entries accordingly, but that then gives me the problem with the articles.
Any suggestions on how to work through this?
