Prokofiev's works have been categorized as barbaric, eclectic, ironic, romantic, post-romantic and anti-romantic, neoclassical, sarcastic, cosmopolitan, cold, industrial, lyrical, full of adrenaline, epic, schizophrenic... It looks like he cannot perfectly match any box our musicologists have been attempting to put him into. It is interesting, that Prokofiev never was paid mechanical royalties by American publishers and record labels during his lifetime, being discriminated against as a Soviet citizen.
