Sure.
The ones I've seen is:
Soul & Jazz being listed as category & genre, each.
Those are not duplicates within the genre or subgenre columns. (which are the actual tags)
If a song was tagged with 'Soul', you obviously want it to show up in the 'Soul' Genre category in MusicBee.
So in the sheet, Soul is present both in the category column, and in a genre column.
User case scenario:
A user should be able to first select a category (the least difficult decision to make), and then be able to e.g. quickly apply Soul as a genre tag.
That's quick and easy, but still correct and adhering to the Genre map. (of which he doesn't even have to be aware of it's existence)
If he wants to be more specific and detailed with tagging it, he could select another Genre that resides under the Soul Category, or a Subgenre residing under the Soul Genre.
And a sidenote to be clear and not maybe confuse some things:
For having music tagged with a genre that:
- is present in the genre map
and/or
- is sourced from Discogs or MusicBrainz
showing up under the correct Genre category in MusicBee, it is essential that MusicBee is also using the custom genre grouping list.
So the Genre map and the Grouping list have related but different purposes.
