My iPhone Music collection has several albums by the same artist. When I select that artist in the Music app I see these albums listed, & "All Songs" at the top. When I select "All Songs" the songs are listed in alphabetical order on track name.
Is it possible to change the "All Songs" order to keep albums together, eg alpha on album name (or numeric on album year), & then by track number within each album? This seems like the most likely way you'd want to play all songs by an artist, so I'm surprised it's not the default & that I can't find a way to do this.
