Copy Album Artist field to Artist field IF empty

Can someone create a script or something that will copy the Album Artist field into the Artist field IF it is empty

I also want this vice versa (from Artist to Album Artist).

Please indicate how to do this mp3tag because I am new to the program and not very good at codes lol.


You could start with reading the FAQs:

Perhaps you also apply a filter with
%artist% IS ""
to show only those files that have no artist...

I don't really have the time to learn the codes just yet lol would someone be able to make one for me? lol

Thanks, I forgot about the search filter.
