Save Multiple Values as separate fields

When an album is by multiple people we store the album credit as it appears on the album as a single value in the Album Artist field and then add each of the main performers as a separate field to the Album Artists field (note the plural). For example an album credit to Johnny Cash & June Carter would store

This has a number of advantages, most players only understand a single value for the AlbumArtist so this way guarantees they get Johnny Cash and June Carter not just Johnny Cash which would be the case if they only took the first value form the Album Artist field. Secondly we preserve the exact album credit, for example this credits using and, but it could be with, ft etcetera. Thirdly the individuals are listed in the Album Artists field, so applications that understand multi value artists can use the Album Artists field instead, this is what MinimServer does.

However some applications such as Roon understand multiple artists, but only use the Album Artist field not the Album Artists field. This option lets you store the album artist as multiple values in the Album Artist field just like the Album Artists field, it also lets you apply the same logic to the Album Artist Sort field, recommended yo select both fields if you use this option.

You can also do exactly the same thing for track artist by selecting the Artist and Artist Sort field as well. All four field are added to this option when using the Roon, Fix Songs profile.

Other people fields such as Composer, Conductor and Producer are always stored as multi value fields because there is no exact credit to preserve.
