Linked below is an explanation I posted a few months ago. As mentioned, the images you see associated with Genres in Roon are influenced by artists in your local library, and tags from our metadata providers. Those genre tags are cultivated from the artist’s main page and individual albums. Albums that are HUGELY popular like the A Star is Born Soundtrack (@Suedkiez "roots rock is also tagged on the album) can place a thumb on the scales due to their reach.
