“A brief word about so-called modern music: no further research or scientific discoveries are required to know with full, objective certainty that it is not music. The proof lies in the fact that music is the product of periodic vibrations—and, therefore, the introduction of nonperiodic vibrations (such as the sounds of street traffic or of machine gears or of coughs and sneezes), i.e., of noise, into an allegedly musical composition eliminates it automatically from the realm of art and of consideration.” —Ayn Rand, The Romantic Manifesto
