Prince’s music is as impossible to categorize as it is to date, as pointed out by MTV’s Brian Phillips. Pick a song from virtually anywhere in his extensive catalog, and you’d be hard-pressed to name what era of his career it was from, let alone what year. This isn’t because he never evolved as a musician—because he did—but because nearly everything he recorded was ahistoric, leading rather than following. He blended elements of hard rock, rap, funk, R&B, new wave, and jazz into a fragrant stew that was just…Prince. In case you haven’t figured it out already, there will never be another.
