Any of y'all out there who have a category you don't consider music have a definition of music that everything you like fits but the stuff you don't consider music doesn't?

Note: I'll not require that stuff you don't like but do consider music either fit or not fit the definition.

BTW, I don't like opera or Amazon River Indian music. There are some, such as gagaku, that I like but can't take more than about 20 minutes of in one sitting.
