As Sivaji became a major anticipated project, several false rumours about the soundtrack of the film were disseminated to websites and magazines. Despite the fact that early on during the project, Vairamuthu confirmed he had written a song called "Vaa..ji Vaa..ji Sivaji", no other major details about any other song was mentioned. Rumours went around that certain singers had sung in the project, including Rajinikanth. However, on 11 October 2006, the source, Behindwoods.com, mentioned that they had received credible information that Sivaji contained seven songs, five of which were set to be in the audio, with the other two being situational songs. Surprisingly, they also mentioned the five songs which were in the album. "Vaa...ji Vaa...ji Sivaji" was mentioned to be the opening song of the film. They also reported that a philosophical song titled "Unpeyar Ennada" was in the film, as per usual Rajinikanth films since Baba. Another song titled "Jee Boom Ba" was mentioned as its picturization was to be filmed in either foreign locations or in Karnataka featuring the lead pair. A song called "Talla Dimi Takka Dimi Pucha" was apparently supposed to contain Japanese lyrics and was set to be filmed in Japan, however the Sivaji crew did not travel to Japan for any purposes during the shoot. The final song mentioned was "Adaal Udan Pesadha Di... En Salangaiku Bhadil Solladi" and it was mentioned as a remix from another film titled Vanjikottai Valiban. Behindwoods.com claimed that this song was set to come in the climax. However none of these possible songs, barring "Vaaji Vaaji", were in the final album.
