nah, but I've taken to sorting my music further into folders such as "Zune," "Zune DRM Free," "Ripped from CD," "URGE Stripped DRM," "Free Music," and "'Free' Music." so it's /source/artist/album.
Anyway, none of this is a big deal. It's too bad that a feature is gone, though... it never got in the way when you didn't want to use it, so why take it out?
