Sorting using replaced words

[simoncn]

I presume these are Album tags. If so, you can add AlbumSort tags to your files and apply these tags as the sort value for Album as described in this section.

In your example, you would only need to add the tag

AlbumSort=Symphony Nos. 4 & 8

to the files that are tagged

Album=Symphonies Nos. 4 & 8

to make the sort order correct. Also, it is sufficient to add this AlbumSort tag to a single file and MinimServer will automatically apply it to all other files with the same Album tag.
