People are tweeting and commenting a lot about the song that is playing at the back throughout the trailer."

I hope this haunting melody stays with them forever. The song was challenging yet exciting, and we discovered a new dimension altogether in music. The entire song is based on an Indian classical Raag packed with contemporary music," he added.
