Are Certain Genres Not "Music"?

While, without seeing your post, I might have opted to present a tautology and say that non-music genres are not music or music genres by definition, since genres refers to categories of artistic composition, and the muses cover the arts and sciences, I will defer to your point in a certain agreement. Music can be considered to be more than sound, but also it can be considered to be less than "just sound" since it commonly implies arrangement.   Traffic noise can be incorporated into music and by itself not be considered music.  Trafficcore, and Post-Traffic, may be music genres, and Traffic is a band, but traffic noise alone might not inspire the muses -- that said, traffic controllers may be inspired by Erato, the muse of erotic poetry and traffic control.  Noise music is a genre of music, of course, but that incorporates "just noise" into a musical framework.  I often think of music generally as simply ordered and sequential notes of sound (though some have attempted one note "music").  That sound need not be musical per se to my ears, but it is structured to be music or must be perceived as music, which can rather depend on the listener.  Music generally is a sort of relationship between the composer and the sound, and the sound and the listener.

As for the "next question", when (if ever or never) is the Art genre not Art when it's an Art Garfunkel?  And what is art, and the limitations thereof, in the garfunkelian paradigm?
