Do you know it. Indian Cinema is Mumbai centric and most of films made are in the language of Hindi however the language of those beautiful melodies are in Urdu. It is a sweet language spoken by millions in India, Pakistan and other countries. I know some people in Punjab(India) have urdu as their first language.
But very little is translated from Urdu into Indian languages. And without that how people of other state would know about this languages. It can happen only when we learn to respect and pay to translators.
