I have a music library that I've been accumulating for nearly 30 years now - so literally gigabytes if not terabytes of data here. I'd like to get all my metadata consistent across everything and some of my music tag data populates the Artist field, but not the Album Artist field. Others do the inversion (Album Artist but not the Artist). Some even have different entries in each column!
In the interests of simplifying my storage, I'd like to have the two fields match one another. So Artist = Album Artist.
Is there a macro way to make this happen in MP3TAG? I am a contributor to the program, as I appreciate the efforts the developer has done here, but there's still a few things I don't see that I'd like to see happen (this being one of them).
