And those are the way to go

But you can also combine both of them: just replace in that second one the `PERIOD` with `GENRE` so that you will put in the GENRE tag field your desired descriptions [which can be important later on, when you will be trying to see those descriptions in some player, that will be able to read the legit GENRE tag field but not some made up field like PERIOD]  
  
  
I personally have been using such combination [although with different descriptions] for something like 4 years now- and it still holds in spite of changing a lot of other things in my naming system and in Mp3tag configuration
