His Royal Badness, Prince Rogers Nelson has said nary a word on the passing of his musical rival, Michael Jackson.Not that he's supposed to, but generally two masters in the same arena acknowledge each other in death, if not in life.The two geniuses were musical opposites in their hey day, pushing each other to new creative heights."Thriller" was met by "Purple Rain.""Bad" was countered with "Sign O the Times."Prince was the do-it-all musician was Michael was the consummate performer.You could be in both camps but you couldn't love both of them the same.That's just how it was.Now that one is no longer with us, the other's absence is stark.
