· It is possible to erase these old entries in the Edit genre mapping window. I just reanalyzed my library after cleaning up all tags and its still showing junk tags in here that no longer exist in music files.
Thanks for your post. I wish we had an easy answer here. Tag pollution can be quite abrasive in Roon because it’s built to retain user edits resiliently. The database will keep a memory of Genre Mappings even when the underlying files no longer contain the associated tags. But the need for some sort of bulk delete is pretty obvious from your screenshot.
Let me escalate this to the team to confirm there’s no workaround that is less tedious than manually nesting these dead tags. In the meantime, the heavy-handed option would be to restore from a Backup before these tags existed.
In the meantime, if you’d like, you can create a feature request for other users to vote on. We’re not casting your report aside, that sub-category simply permits other users to vote on the post:
Just to add that genres that are created in Roon directly can’t be deleted either, so if you make a mistake by creating an unnecessary genre manually, you are stuck with it. (The only partial workaround is to create a cemetery genre to move them to)
