Adding setting for description display

[simoncn]

What is you current setting for upnpCustom? It should be empty.

If the AlbumArtist is tagged and your upnpCustom setting is correct, the AlbumArtist should be shown in the first screenshot (list of metadata). No other settings in MinimServer are needed to make this happens. You might need to restart MinimServer and reload the MinimServer library into BubbleUPnP.

For the second screen (Now Playing), BubbleUPnP shows the Composer but does not show the AlbumArtist. The only way to show the AlbumArtist on this screen is to use tag formatting to add it to one of the fields that is shown by BubbleUPnP (album, title, artist or composer).

Alandbush has provided an example of how you could add the AlbumArtist to the Album field.
