Rock On!! is the soundtrack to the 2008 musical film of the same name directed by Abhishek Kapoor, starring Arjun Rampal, Farhan Akhtar, Purab Kohli and Luke Kenny. The original score and songs were composed by Shankar–Ehsaan–Loy. The songs' lyrics were written by Javed Akhtar.

The album was released on 7 July 2008.^{[citation needed]} by Big Music Despite a cold reception from the critics, the album became a cult favourite selling over 120,000 copies in India.^[1]

The movie's songs were composed in five days. 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. All songs were mixed by Vijay Benegal.

"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. This was followed by "Socha Hai" and the title track "Rock On!!". These were sung by Farhan Akhtar in his first singing role. "Yeh Tumhari Meri Baatein" is sung by Dominique Cerejo in an ambient genre. "Zehreelay", performed by Suraj Jagan, is hardcore metal, which is often a rarity in mainstream Bollywood soundtracks.

The rock ballad "Tum Ho Toh" was sung by Farhan Akhtar. "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 song is performed by Farhan Akhtar and Raman Mahadevan. The serene "Phir Dekhiye" is performed by a long-time favorite of Shankar–Ehsaan–Loy, Caralisa Monteiro. The album also has a live version of "Pichle Saat Dinon Mein".^[2] Darshan Doshi, the drummer who also tours with the trio, Shankar–Ehsaan–Loy's band, played the drums in the soundtrack.^[3]

Bass guitar was played by Ardeshir Mistry (Adi Mistry), (who plays with Blackstratblues, Amit Trivedi etc..)

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.^[4]

The music was released worldwide by Big Music on July 7, 2008, at Infinity Mall in Andheri, Mumbai. Shankar–Ehsaan–Loy and Farhan Akhtar performed live at the launch with rest of the cast.^[5]
