Hi Brad,
I’ve shifted your post into this Feature Request because Roon cannot currently sort Album by Composer and it remains a feature request.
You can sort Classical albums using Albums/Focus/Genre/Classical and make a Bookmark to recall that view with a click. You can also click that Focus from + to - in order to view all Albums that are not Classical.
Within that Classical focus you can sort by Artist, but, as I’m sure you will agree, that is not the same as sorting by Composer.
You can also view your Roon library by Composer, but that is Work based, which is not always what you want.
I would still very much support a Sort by Composer view in Albums, Tracks, Genres etc. so lets hope that this Feature Request gets sufficient support to become a thing !
