Deletion of Honorific titles in popular music

Comment: seems too subjective ( -ish) who is included.  BBC for instance has Kylie and not Britney as "Princess of Pop" http://news.bbc.co.uk/1/hi/entertainment/6139654.stm and Guardian cites Jimmy Cliff as "King of Reggae" http://music.guardian.co.uk/world/story/0,,2284219,00.html.  Either the choice is going to end up subjective or its going to be an infinitely extending list whenever a journalist used 'king' as hyperbole. Top sellers by genre would tend to get you the same sort of info but be easier to define
Stance: delete
