ALBUMARTIST if ARTIST

Support

This works better than I have imagined it could; because it says exactly what is missing and I need to use only one column for this

I only had to adjust the gradation of importance:
1] ARTIST
2] ALBUM
3] ALBUM ARTIST

And so:

$if(%ARTIST%,$if(%ALBUM%,$if(%ALBUMARTIST%,'Albumartist exists','Albumartist missing'),'Album missing'),'Artist missing')

And here is a version even more adjusted to my likening $if(%ARTIST%,$if(%ALBUM%,$if(%ALBUMARTIST%,'+ OK +','- Album Artist'),'- Album'),'- Artist')

Thank you very much
