Prince

"In a career that spanned five decades, Prince really did change the world. After making some of most inventive albums of the 80s - including 1999, Purple Rain, and Sign "O" The Times - he turned his attention to redefining his role in the music industry, changing his name to an unpronounceable symbol, declaring war on Warner Bros, and leading the internet revolution. When he died, on April 21 2016, the world lost one of the few artists who could truly claim to be called a genius. His legacy lives on, and will remain an inspiration for all time.
