Category talk:Musical duos

Entries should be removed from here and added to Duo subcategories?? Why?
"Rule" or edict makes no sense .. so what if Category is long? It's alphabetized into sub headings. I think this opening warning is not needed at all. " 'Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.'" From Peter aka Vid2vid (talk) 21:29, 17 August 2019 (UTC).
