Multidisc and Genre Subtitle tags conflicting

[simbun]

Up until now each album has only comprised a single disc (has a DiscNumber of 1 or is empty) so MinimServer hasn't attempted to merge across folders to form an album, but this particular album has multiple discs so - given the "normal" file structure is to have one disc per folder - MinimServer merges across folders using AlbumArtist and Album to form an album.

One way to prevent this is to use match filters as described at the bottom of the 'Albums and folders' section.
