Royals is a fairly unique pop song for which I give kudos. As for an "awful" melody, I am not sure what that means other than "Saddam doesn't like it" which is fairly irrelevant. The Grammy's are only really concerned with popular music, so within that field I feel they chose a deserving winner; it's definitely got more substance than the average Rihanna or Katy Perry fare or the faux-fringe of Lady Gaga.
