Hello again 
I have some files that have no tags at all, but the filename consists of them. Here is an example:
Birth Control - Birth Control - Gamma ray song.mp3
So, the artist comes twice.
Plus, at the end of every filename, there is song before the extension.
So I tried to get the tags from filename with
`%artist% - %artist% - %title% song
But then I get “Birth Control; Birth Control” as artist.
How can I achieve that it’s only once shown?
