Does Picard have a variable for the release’s artist?
albumartist is the release’s artist as credited, which is slightly different, as it can change from one release to the next. It’d be really neat to be able to better group together all releases by a single artist alias, regardless of designers replacing “and” with “&” and so on.
As a stopgap measure, it looks like
albumartistsort is based on the artist, as the artist-as-credited doesn’t seem to have its own separate sortable version, which makes sense. So using that in Picard for the artist name should group them nicely, albeit looking overly formal.
