I use MusicBee to organize my music library, and the nice thing is that it allows for multiple genres. When I store multiple genre tags on one album, it'll show this in Mp3tag with as follows:
Genre 1\Genre 2\Genre 3\etc
Now I decided that I wanted to change all music I have tagged as "Melodeath" to have its genre tag changed to "Melodic Death Metal". However in every batch way I try to do this, it gets rid of all the other genre tags as well. So far I tried the function
$replace(%genre%,Melodeath,Melodic Death Metal)
but that doesn't work. I learned that Mp3tag treats the double backslash as a tag separator, so it creates multiple genre tags in the file. Is there a way I can circumvent this while replacing in batch?
