I was just hoping for suggestions about how users should display this sort of essential information if not in the grouping field. A number of download sites uses the grouping field in this way, so it's not merely a whim of Audirvana. And it does provide a way in which Classical works can be tagged and be presented in a helpful and clear way - the form familiar from record sleeves and CD booklets.
I've spent a long time editing the grouping field to hold this 'work title' information. I'd be happy to move it into another field if there was another one in JRemote that could be made to display it effectively.
Earlier in this thread it was suggested using the disk # field, and I've tried this, but of course it's not a text field and you can't change the field type.
My other point was about the composers name. If I play a Beethoven Symphony the composers name doesn't appear on the Main JRemote playing screens, unless it's in the individual track title. Whereas it will be in the Composer field. I've also added it to the front of the album title tag, but the album title doesn't appear on the main screens either, if the orchestra and conductor (album artist) happens to be more than four or five words long.
Leaving aside the specific question about groupings, is it possible that JRemote might at some point allow users more choice about how any of these tags appear on screen?
