Sorry, but since I have zero interest in today's pop music, I am suggesting it for classical only.
That's taken for granted. My point is that the system was created by people who know nothing about anything except pop music. Why is there an "artist" line - for van Gogh? Why are there not tags for "orchestra", "conductor", "pianist" etc? Why is there a tag for "album"? So you can collect stamps? It's all predicated on pop music.
Yes, it is "unprofessional" and "semantically oblique"..but by manually populating the tag fields( esp COMMENTS) to embed the documentation I will not be searching for it elsewhere. Now back to the main thread,,
