I use Musicbee, which expresses multiple genres like this:
“Genre A; Genre B; Genre C”
I like to manually tag the genres for my music files, so I click “Add to ‘Preserve Tags’ list”. This does preserve the tags; however it replaces the semi-colons with a slash, which Musicbee doesn’t recognise as multiple genres. Essentially I would have to manually retag the genres for every file in my collection, which would take a huge amount of time.
Is there any way I can stop this from happening? I’ve attached a picture so you can see what I mean.
