Exclusive music album premiere of the much awaited movie of the season â€“ Karan Johar's 'Student of the Year' on 'Kasa Kai Mumbai'. The starry presence of director Karan Johar, debutantes Varun Dhawan, Sidharth Malhotra and Alia Bhatt added bling to the launch. The album follows on close heels of the now popular 'disco' song from the movie that had been released 2 days before on Radio City 91.1 FM. Karan Johar said, This is a proud and exciting day for all of us at Dharma Productions. The response to The Disco Song has been phenomenal while debutants Alia, Varun and Sidharth have instantly been able to connect with the audiences. This film launches 3 new talents and is a celebration of youth, music and dance to make sure that our ambitious soundtrack connects to a worldwide audience.
