Multiple artist tag in FLAC files

In the MP3 files I have, minimserver is able to split them so the track appears under both artists' index. However, for FLACs they just appear in the artist index as "artista/artistb".

Is this a limitation of Vorbis and/or is there a workaround? Or am I missing a step?

For FLAC/Vorbis, the file needs to contain multiple Vorbis comments as follows:

ARTIST=artista
ARTIST=artistb

If you are using Mp3tag as your tagging program, you would write this as artista\\artistb and Mp3tag would create the above two Vorbis comments.

The same principle applies to MP3 files but there is a slight complication. MP3 files can contain either ID3v2.3 or ID3v2.4 tags. For ID3v2.3, multiple artist values are separated by "/", so artista\\artistb happens to be equivalent to artista/artistb for ID3v2.3 only.

Separating artist values by "/" isn't a good idea (it doesn't work if the artist name contains a "/") and this was changed in ID3v2.4 to use a better approach of separating multiple values with the NUL (0x00) character for all tags (not just for artists) . If you write artista\\artistb in Mp3tag, you will get correct results with ID3v2.4, but you won't get correct results if you use artista/artistb.

The MinimServer recommendation is that you should always use artista\\artistb (or the equivalent in your chosen tagging program) and you should use ID3v2.4 in preference to ID3v2.3.
