Quincy Jones is probably the most influential person in the music industry as he has lent his musical talents to everyone from Ray Charles to Michael Jackson.Speaking at a Spotify launch event, Jones said that Diddy “couldn’t recognize a b flat if it hit him.” Instead, Jones noted, “P. Diddy has a doctorate in marketing,” citing his clothing labels and success with Ciroc as the Bad Boy‘s true talents. Quincy didn’t just bring up Diddy, he was asked a question regarding the mogul and he responded with the above criticism.
