Artist Tag If No AlbumArtist Tag?

[simoncn]

You can use the tagValue property to do this.

1) Add a new tag to itemTags, for example ArtistFormat
2) Set tagValue to ArtistFormat.default={AlbumArtist, Artist}
3) Change your tagFormat settting to: Album.displayFormat={$artistformat^^ / $album^$date^ (^)}

Note the slight change to your format string to improve the formatting for albums with mutliple artists.
