Here is an example of what I mean
So I have this album which has music composed by Sergei Rachmaninoff, played by Vladimir Ashkenazy, and the album credited to Rachmaninov; Vladimir Ashkenazy, Concertgebouw Orchestra, Bernard Haitink

https://musicbrainz.org/release/219e0252-c483-47bd-9215-5db22356a93d
And if we have a look at the Sergei Rachmaninoff alias page we see (obviously) that his primary name is Π‘Π΅ΡΠ³Π΅ΠΉ ΠΠ°ΡΠΈΠ»ΡΠ΅Π²ΠΈΡ Π Π°Ρ
ΠΌΠ°Π½ΠΈΠ½ΠΎΠ² but notice the third line in the table Sergei Rachmaninoff is labelled as English (primary)
Default Config
Now with the SongKong defaults:
Format:Romanize non-Latin script artist names wherever possible:Yes
Format:Use Standard Artist Name instead of Name displayed on Cover: Yes
Classical:Remove Composers from Album Artist:No
We get the following
Album Artist:Sergei Rachmaninoff; Vladimir Ashkenazy, Koninklijk Concertgebouworkest, Bernard Haitink
Composer:Sergei Rachmaninoff
Because we use the standard name, using English (primary) version of non Latin script name if available
Config Two
If we set to Format:Romanize non-Latin script artist names whereever possible to No so we have
Format:Romanize non-Latin script artist names wherever possible:No
Format:Use Standard Artist Name instead of Name displayed on Cover: Yes
Classical:Remove Composers from Album Artist:No
we get
Album Artist:Π‘Π΅ΡΠ³Π΅ΠΉ Π Π°Ρ
ΠΌΠ°Π½ΠΈΠ½ΠΎΠ²; Vladimir Ashkenazy, Koninklijk Concertgebouworkest, Bernard Haitink
Composer:Π‘Π΅ΡΠ³Π΅ΠΉ Π Π°Ρ
ΠΌΠ°Π½ΠΈΠ½ΠΎΠ²
because now we stil ignore the album credited name and go to the artist entity but for non Latin we dont use the artists entities English name anymore
Config Three
If we also set to Use Standard Artist Name instead of Name displayed on Cover to No so we have
Format:Romanize non-Latin script artist names wherever possible:No
Format:Use Standard Artist Name instead of Name displayed on Cover: No
Classical:Remove Composers from Album Artist:No
we have
Album Artist:Rachmaninov; Vladimir Ashkenazy, Concertgebouw Orchestra, Bernard Haitink
Composer:Π‘Π΅ΡΠ³Π΅ΠΉ Π Π°Ρ
ΠΌΠ°Π½ΠΈΠ½ΠΎΠ²
Because now for the album artist we just use however they are credited and they are credited as Rachmaninov as the album artist, but in this case the composer comes from the linked work and here is just credited as Π‘Π΅ΡΠ³Π΅ΠΉ ΠΠ°ΡΠΈΠ»ΡΠ΅Π²ΠΈΡ Π Π°Ρ
ΠΌΠ°Π½ΠΈΠ½ΠΎΠ², so that is why there is a difference.
Config Four
If we change to:
Format:Romanize non-Latin script artist names wherever possible:Yes
Format:Use Standard Artist Name instead of Name displayed on Cover: No
Classical:Remove Composers from Album Artist:No
we get
Album Artist:Rachmaninov; Vladimir Ashkenazy, Concertgebouw Orchestra, Bernard Haitink
Composer:Sergei Rachmaninoff
Because we are romanizing the composer credit because it in Cyrillic, but not we are not romanizing the album artist credit Rachmaninov because not in Cyrillic and we havent asked to use standard name.
Config Five
Also if we enable Classical:Remove Composers from Album Artist to Yes then we see that he is removed from the album artist field completely
Album Artist:Vladimir Ashkenazy, Concertgebouw Orchestra, Bernard Haitink
So you can see it is quite complex but for most customers the defaults give the best results.
