He was a genius. That word gets tossed around too casually at times but it truly fits him; he was a genius, akin to Mozart. As others have pointed out he was very skilled on more instruments than most people can even name. He sang like an angle, wrote some of the most iconic songs of the last 30 years, penned the biggest hits the Bangles and Sinead ever had and was widely regarded as one of the best guitarists alive until today. His passing leaves a space that no one will be able to fill.
RIP, Prince!
