I gave up the whole "my music is better than your music" conceit long ago. Objectively, there is no good music, nor any bad music. Music simply is, and all subjectivity resides exactly where Dewey Redman said: in the ear of the behearer.
If someone prefers listening to Kamasi Washington, shut up and let them. If someone prefers to listen to Paal Nilssen-Love, shut up and let them.
Lastly, don't ever tell anybody what is and isn't good music, or why yours is better than theirs. Might as well tell them their favorite food should be spaghetti because it's your favorite.
