Emraan Hashmi for the FIRST TIME EVER!! We see the Serial Kisser groove to the beat and Rap. He creates his own song with his co star Humaima Malik and director Kunal Deshmukh. The song is called " Coz That's How I Roll". Hesitant Emraan becomes Hipster.
P.S: If the song doesn't make any sense you are on the right track.
