Kajra Re
Kajra Re () is a song composed by Shankar–Ehsaan–Loy, written by Gulzar and sung by the playback singers Alisha Chinoy, Shankar Mahadevan and Javed Ali. It is from the 2005 film Bunty Aur Babli, starring Amitabh Bachchan, Abhishek Bachchan and Rani Mukerji. Aishwarya Rai plays a courtesan trying to express her desires to attract the male, or her client. It features Amitabh and Abhishek at a nightclub and Aishwarya Rai, making a special appearance in the film, sings for Amitabh while ignoring Abhishek's approaches. Amitabh eventually joins Abhishek and Aishwarya in the singing and dancing.

Production and development
Kajra Re is inspired from a folk song from the Braj region, in which the celebrated dark eyes are Lord Krishna's. The words "Tujhse milna Purani Dilli mein..." ("...meet you in Old Delhi") have been rendered by Amitabh Bachchan. It was a very famous "item number" from the movie Bunty Aur Babli. Uncommon to other "item numbers", the music was influenced by the genre of kajari.
The trio have used sitar to make it sound more Indian. Amitabh Bachchan, after initially hearing the song, demanded a few changes, but the director, Shaad Ali, and producer, Aditya Chopra, convinced him against them. The song was composed in half a day. Alisha was chosen for the female vocals since her anglicized accent was meant to provide an essentially different intonation.

Reception and impact
The melody of this song was used as the main method to promote the film and the soundtrack. The song became extremely popular among the masses and was hugely successful on Indian music charts. The Hindustan Times described it as "the reinvention of the qawwali by Shankar-Ehsaan-Roy and Gulzar" and called it "the item number of the decade." Kajra Re featured on top in Rediffs 2005's list of top 5 songs. It also won the poll conducted by Planet Bollywood as the song of the year with a whopping 44%.

It was voted as the song of the year by three radio stations, including Lotus FM, a station popular among the Indian diaspora in South Africa. The song was also featured in Caminho das Indias, a marathon telenovela that ran on Brazil's popular Rede Globo. The track was featured in Hindustan Times' Songs of the Century, which deemed it to be the "undisputed item song of the decade."

Music video
Before the song sequence, Amitabh Bachchan, playing a cop in the movie, relates his story of unrequited love in the city of Delhi to Abhishek Bachchan (his real-life son who plays a criminal pursued by the cop), which is later alluded to in the song. Aishwarya Rai's character, a bar girl, sympathizes with Amitabh's character and plays courtesan. The dance, choreographed by Vaibhavi Merchant, features Aishwarya in a brocade choli and dipped ghagra, kohl, and some lip gloss.

Awards
Alisha Chinai won the 2005 Filmfare Best Female Playback Award and the 2005 Bollywood Movie Award - Best Playback Singer Female for the song, while Gulzar collected the best lyricist award in almost all major award functions including the IIFA and Filmfare Awards, for the song.

Zee Best Choreography Award
Star Screen Awards - Best Choreography
