Just trying to figure out if I get your suggestion correct…
You’re asking for a music library displayed by albums to support a sort order where the albums are listed by…
- artist name
- album name
- album release date / year
This should sort same-named albums of the same artist by their release date.
Or are you asking for the albums to be sorted by…
- artist name
- album release date / year
There’s been a recent discussion regarding Plexamp pointing out that the app behaves slightly different from other Plex clients when it comes to sorting albums by artist (Plexamp: Artist > Release Date; other apps: Artist > Album Name). Elan has commented in that thread that they’ll start respecting the library option Album Sorting (which is currently only controlling how albums are sorted on an artist page) for the library being displayed by albums.
