Well, I had lightly complained last year that my Roon Radio seemed to default to Opera and I wondered how to stop it. The suggestion was to give it a thumbs down whenever Opera showed its ugly head.
Well, after many, many thumbs down it seems to have gotten worse.
Others have complained of the same thing (example here)
So that is my feature suggestion … or maybe it’s a bug fix? Treat classical music categories (symphonies, concertos, sonatas, chamber, opera) like popular music (heavy metal, vocalists, elevator music, rock, country, etc)
Or better yet, delete all opera recordings (grin)
