Is there really a mystery. All of these gentleman judges are culprits of employing tactics that go beyond fairness and professionalism. In the latest episode, both ID and HR are on fault. Why did ID do a drama of walking out when its public votes and not judges numbers that decide winners (Nihira got better marks from judges yet was voted out by public!!..shame). And HR..well he should not have been a mentor anyway..completely unprofessional and incompetent musician. He is bad for show..throw him out ASAP
