Lotsa answers coming in here. I’ll keep mine brief, though.
Prince is probably the greatest musician of all time, if you ask me. Nobody can match the diverse pop-funk style he used and grew throughout the 80’s and 90’s. He admittedly fell off a bit in the 00’s onwards, but that was only after about twenty banger albums.
Also, uh, shoutouts to Buckethead and Linkin Park.
