yes, scrolling through thousands of tags is not practical. What is the normal procedure?
Sorry, there is no normal.
The matter of genres and digital music managers is still un-treaded territory in many ways.
Maybe in the future - while I'm typing - suitable suggestions from the previously available central genres can be displayed for selection?
MusicBee already does that.
For the songs existing in your library, the genres known for those songs should come up when typing a genre entry.
But I am guessing the songs in your library don't have the thousands of genres I was speaking of earlier, and you are trying to add a genre that's not yet known in your library?
What you could do:
I have created a test set of tracks that all together contain all the (near 3000) genres that are in my 'enhanced genre hierarchy' table.
You can find it here:
