I am new in MP3Tag. I must say that it looks very very amazing application. Anyway, I am using Plex for my music and it seems that it likes to have an Album Artist in order to show nice in the list. I would like to copy all my Artist field to the album Artist, for all the songs in my list. I am sure this is possible, but i have no idea how to make it happen...
Thats because you are writing the content of the composer-tag to the artist-tag.
As the composer-tag is empty, the artist-tag will get empty too.
You have to do it the other way round:
