Great musician; but since everyone is kissing his ass, and since his family probably doesn't post here, here is a little balance: Trent Reznor from NIN in 1994, talking about meeting Prince.
"Prince was working in the same studio here the first day I came in, and one of his techs said to me: "Hey, Prince likes your stuff, he had your Broken CD in the car, and he later actually told his people to mix their tracks harder, and it might have been due to hearing Broken." I thought they were kidding, because this is a guy whose work I respect immensely. I figured it might just be cool to say 'hi' if I ran into him around the studio. Soon after that I find myself at one end of a big long hallway, and he's at the other end, walking towards me. So I simply said "Hi", and waited for him to make eye contact. He just turned his head away, and walked past me. That strikes a wrong chord in my Midwestern upbringing, regarding simple human decency. I don't mean to sound judgemental, but I've no great desire to meet Bowie now, because in my mind, I'd rather think of him as this cool guy."
Ironically, Trent would later go on to not only meet Bowie, but get invited on a very successful tour with him, and become friends for life, even getting advice from David to clean up his act. Because Bowie was apparently a really nice guy. Prince... not so much.
