Still confused by Artist, Albumartist and ArtistSort

[Mangar]

Hi,

first I wish a Happy New Year to everyone!

I have mostly Albums by one artist and only a few compilation albums with many different artists. Beause of that I tagged my albums like the following example:

Artist: Gary Moore
AlbumArtist: Moore, Gary
ArtistSort: Moore, Gary

My tagOptions: Artist.reverseName.display, AlbumArtist.reverseName.display

Everything is fine this way.

But now I started to rip all of the CD's of my father and he has many compilations like this.

When I tag it automatically by MP3Tag with Musicbrainz as source, I get the following:

Artist: Clous van Mechelen
AlbumArtist: Various Artists
ArtistSort: Mechelen, Clous van

Artist: Gerry Mulligan
AlbumArtist: Various Artists
ArtistSort: Mulligan, Gerry

First question: Is there a besser way than "Various Artists" in the AlbumArtist? With my few compilations like Metal Ballads I overwrote "Various Artists" just with the album name, in this case "Metal Ballads".

Second question: Is this by design, that MinimServer show AlbumArtist under Artists and Artists under All Artists? So someone who has mostly compiliations should use All Artists instead of Artists when browsing?

Third question: How can I force MinimServer to use ArtistSort if not empty else Artist? Or is it recommended to always write the Artist in the format Surname, Firstname?
