I enjoyed watching the video, and not for its hilarity. In fact, what I felt the music conveys is a great sense of chaos, anger, and desperation, some alienation too.
I have not done analysis, and am unfamiliar with the score, but I am very skeptical of those who call this garbage, as I recall the same reaction meeting great works of Beethoven, R. Strauss, Stravinsky, Antheil, Boulez, Ligeti, and a myriad of other great composers. Eerily, almost the same words: this is not music, it is cacophony (on Beethoven's 9th); this is the music of a madman (on Stravinsky's Rite of Spring); the ear cannot comprehend garbage like this (on R. Strauss Salome); this is not music (too many to single out, but certainly Antheil's Ballet Mechanique fits the bill).
You may not like it, you may laugh at it, and you may choose not to subsidize it, but I find it limited to not aknowledge it is art.
