UNESCO declares Indian National Anthem best in the world: True or false?

This email message has gone viral on Facebook and Whatsapp again. It appears to have first emerged in 2008 to till date.

A Facebook page has also been created asking Indians to be proud because the Indian National Anthem has been declared the best in the world by UNESCO.
Jana Gana Mana is based on a Bengali-Sanskrit poem written by Rabindranath Tagore, India‚Äôs great poet and author of pre-Independence era who had also put his poem to tune.
