“Album by Artist” sorting in iTunes

So there is nothing new about this feature; it has been around for quite a while.  I don’t really understand the idea of not sorting like this, as it is alphabetical by artist, yet it organises albums in track order even if they have multiple artists. But for the longest time it didn’t work with one of my albums (8BP050—an awesome collection of 8-bit).

Of course I had the compilation option ticked. That is the usual issue, but not mine. Well I just figured it out: if you have this issue, make sure that the “Album Artist” field is empty for all the tracks in the album.
