Ranbir Kapoor's character sings to overcome his stutter

Singer and musician Tushar Joshi has watched 'Jagga Josoos' 50 times. And no, he isn't a Ranbir Kapoor fan. He is his voice in the film. If you have seen the movie, you know that Jagga, the character Kapoor plays, stutters. To avoid this stutter, he resorts to singing in order to communicate. Joshi's repeated watching of the movie was, hence, to get into the character and get modalities of tone and emotions right.
