Music Assistant applies disliked genres to radio, dynamic playlists and every Autoplay mode. A listener can exclude a whole genre from automatic selections alongside the existing exclusions for individual tracks, albums and artists. Tracks, albums and playlists chosen manually are not filtered.
The check uses the library’s genre information. Tracks with their own genres use those; otherwise the genres of their albums apply. A track that has no matching library entry is not excluded by genre, so this does not promise to filter every recommendation returned by an outside music service.
