It is the Hindi version of a Tamil number composed by Nucleya and rendered by Benny Dayal. Says the film's director Shakun Batra, `Since this is not a film where you can do justice to seven tracks, we decided to have an extra track and use it for promotions. It is very groovy."

"It is the Hindi adaptation of a Tamil song, so when you see the video, it starts off with scenes from the original video and Bharatnatyam dancers before moving to the Hindi part," he adds.
