Shankar–Ehsaan–Loy and Farhan Akhtar performed live at the launch with rest of the cast. The music was released worldwide by Big Music on July 7, 2008, at Infinity Mall in Andheri, Mumbai. The lyrics of 'Rock On!!' were written by Javed Akhtar like a modern rock band's output - and yet acceptable to the film audience - and have some depth without sounding like spoofs, parodies or comedy numbers. īass guitar was played by Ardeshir Mistry (Adi Mistry), (who plays with Blackstratblues, Amit Trivedi etc.) Darshan Doshi, the drummer who also tours with the trio, Shankar–Ehsaan–Loy's band, played the drums in the soundtrack. The album also has a live version of 'Pichle Saat Dinon Mein'.

The serene 'Phir Dekhiye' is performed by a long-time favorite of Shankar–Ehsaan–Loy, Caralisa Monteiro. The song is performed by Farhan Akhtar and Raman Mahadevan. 'Sinbad The Sailor' is the song that appears in the climax of the movie, which is along the lines of ' Achilles Last Stand' and ' Tales of Brave Ulysses'. The rock ballad 'Tum Ho Toh' was sung by Farhan Akhtar. 'Zehreelay', performed by Suraj Jagan, is hardcore metal, which is often a rarity in mainstream Bollywood soundtracks. 'Yeh Tumhari Meri Baatein' is sung by Dominique Cerejo in an ambient genre. These were sung by Farhan Akhtar in his first singing role. This was followed by 'Socha Hai' and the title track 'Rock On!!'. 'Pichle Saat Dinon Mein', a song about how one loses everything but cannot afford to lose love, was the first song composed, jammed on the guitar riff that Ehsaan Noorani came up with completed in about 20 minutes. Since the movie is about a rock band, Shankar–Ehsaan–Loy composed the music in a similar fashion, with the drums and bass set-up and played live to the recorder without any programming. The movie's songs were composed in five days.
