The function was attended by Milkha Singh and the film's stars, Farhan Akhtar and Sonam Kapoor. The album was officially launched later on 19 June, along with the film's theatrical trailer. However, due to increasing demand of the fans after the promos, Sony Music and ROMP decided to release the music online digitally a week before on 14 June. The soundtrack was initially planned to be released on 21 June. The music rights were sold to Sony Music, who had produced the soundtrack to Mehra's earlier film Rang De Basanti. The reunion took place while Mehra visited the Kingdom of Dreams, where the trio had performed, and they brainstormed back at the hotel and came up with ideas for the music for the film. But due to Rahman's packed schedules he turned down the film and Mehra opted for Shankar–Ehsaan–Loy trio with whom he had collaborated before for various other projects. Rahman was expected to compose the soundtrack for the film as with previous two films of Mehra.
