Gemini is the soundtrack album for the 2002 Tamil film of the same name directed by Saran and features music composed by Bharadwaj with lyrics by Vairamuthu.

According to Vikram, the song was recorded and filmed the same morning, and was added to the soundtrack album a month after its initial release.

[23] The song enjoyed anthem-like popularity[24][25] and according to V. Paramesh, a dealer of film music for 23 years, sold like "hot cakes".

The high-energy track "O Podu" drove youngsters insane; some resorted to violence, enraging villagers in Tamil Nadu and damaging public property in Malaysia for fun.

[36][37] The lyrics by Vairamuthu, which are typically in pure Tamil, contained slang and words from other languages like "Deewana" (Hindi).

In an article that scrutinised and decried the high level of vulgarity depicted in south Indian films, Sudha G. Tilak of Tehelka wrote that hit tracks like "O Podu" were "obvious in their debauched suggestiveness".

[46][47] In September 2003, physical trainer Santosh Kumar played "O Podu" among a range of popular music as part of a dance aerobics session in a fitness camp held for the India national cricket team at Bangalore.

[49][50] The movement urged the electorate to exercise the right to reject candidates under Section 49-O of The Conduct of Election Rules, 1961, wherein a voter, who has decided not to vote for anyone, can record the fact.

[51] For this purpose, the people behind "O Podu" also urged the election commission to facilitate a separate button on the electronic voting machine.

[51] During the 2010 Asia Cup, a Sri Lankan band performed "O Podu" at the India vs. Pakistan cricket match held in Dambulla.

[52] In July 2011, Vikram inaugurated "Liver 4 Life", an initiative launched by MIOT Hospitals to create awareness of the Hepatitis B virus.
