Apple TV - Sort playlist in Apple Music by Artist
I just found a way to do this after many trials and errors.
I am on a Mac running Ventura 13.4.
1). Create a brand new playlist (File, New, Playlist). It does NOT work if you select your content and then right click and do "Add to Playlist, New Playlist".
2). Select the content you want for your playlist. In my case, I selected the pre-existing view called Music Videos.
3). In that view, in the upper right corner, click on the bidirectioan up/down arrows and then choose Director and Title. In my case, this sorts the content by Artist / Director and it groups the content into albums of the same name.
Then, drag your content onto the Playlist and release.
When you go to that Playlist in Apple Music on the Apple TV, it should now be sorted by artist, by album.
Hope that helps.
