Please be logical and vote for the best singers. Do not let your emotions fool you. Do not vote based on looks/region/religion/state/village/city etc.
People are different. They will consider different singers as best. There wont be an anonymous choice. But that is allright as long as it is based on the performance on stage.
In elections also we vote based on emotion sans any logic. Politicians have been exploiting this and dividing us on the basis of caste/language/religion etc.
This is your chance to vote for the person whom you consider to be a better performer.
