3 Idiots is the soundtrack to the 2009 Indian Hindi-language film of the same name written and directed by Rajkumar Hirani and co-written by Abhijat Joshi.

The soundtrack featured five original songs and two remixes composed and produced by Shantanu Moitra and lyrics written by Swanand Kirkire.

Shantanu Moitra said the track "is kind of a tribute to the great Hindi film love songs" and also praised its picturisation.

[5][6] Though Aamir Khan initially disapproved the idea of a low-key music launch, he felt that the unique promotion may work in favour of the film.

[6][7] Song promos were aired in television channels and online streaming sites during December 2009, prior to the film's release.

[13] In addition, the track "Kaise Mujhe" composed by A. R. Rahman for Ghajini (2008), which also had Aamir Khan in the lead, and the same music company distributed the album, was featured in the B-side of the LP record.

[13] The songs were attached with the "Premium" and "Collector's Edition" discs launched by Reliance Big Home Video during early-October and late-November 2010.

[15][16] Joginder Tuteja of Bollywood Hungama gave 3.5 stars (out of 5) stating it as "a good quality album" and "the strength of the film which translates in the box-office success".

"[18] Indo-Asian News Service-based critic writing for Hindustan Times said that "the album is a good mix of slow and fast-paced songs.

[23] According to the Indian trade website Box Office India, the album was the highest-selling Bollywood soundtrack of 2009,[1] with about 1.5 million sales.
