Track Ordering Issue with DiscSubtitle

[simoncn]

I think you have this reversed. multiTag tells MinimServer to send multiple artists (etc.) in multiple DIDL-Lite tags (hence the name). Without multiTag, all artists (etc.) are merged into a single DIDL-Lite tag value. The "tag" in "multiTag" is a DIDL-Lite XML tag, not a metadata tag.

multiTag was introduced at the request of the developers of the LUMIN app. They wanted a way to download the entire library and parse the resulting DIDL-Lite into artists, etc. Using a comma as a separator to parse a merged DIDL-Lite artist value doesn't work because an artist name might include a comma.

As most control points couldn't handle the multiTag format (even though it is compliant with the UPnP specification), it was enabled only by this special option.
