CHRISTINA AGUILERA "DIRRTY"
I WAS quite suprised by this one, cos it's not really got that much of an Ohrwurm-ish melody. But, worryingly, I woke up with it in my head, and it's been there most of the day so far.
  Yelena emailed me and said, "If you sing Rio by Duran Duran to yourself while you have another song in your head, the first song is removed from oppressive memory and Rio refuses to infect your brain."
  Now is the time to try it out, I think...
