beet modify artist='$albumartist'

[6OmpH9]

All I want to do is replace the artist tag with the contents of the albumartist tag,
In the documentation I saw that beet modify artist='$artist_sort' is possible to replace the contents of the artists field with the artist sort field, So I tried beet modify artist='$albumartist' but it literally replaced the artist info with the words "albumartist".

I have tried using beet modify artist="$albumartist", beet modify artist=${albumartist} both resulted in the artist field being left empty.

The reason I want to do this is for example if I import "The last waltz by the band" and then use that library in something like jellyfin I'm going to end up with the least twenty artists I don't want displayed in the artist's section, The Gorillaz is another band almost not worth including due to the number of junk artists it'll add to jellyfin.

Anyone else found a convenient way to deal with this?
