The actor will be singing two songs in this film that is set to release a single soon

First it was Evandi Unne Petthan… from  Vaanam. Then it was Vilayadu Mankatha… from  Mankatha. Now, it is Vosthi starring Simbu and Richa Gangopadhyay, which will have a single track being  released, well before the official
audio launch of the film. Confirming the news, Thaman, the music director of the film, says, “Yes. We will be releasing the title track of the film shortly — possibly within a week or so. The song is in the postproduction stage.” Simbu, who is known to croon a number in almost all his films, will be singing in Vosthi as well. A source confirms to CT that Simbu will be singing two songs in this movie. “One will be a mass number and the other one will be a duet with Shreya Ghoshal,” the source adds. What remains to be seen however, is if Vosthi will have a Munni badnaam hui… number. “The team,” Thaman informs, “even considered dubbing the same song to Tamil. However,
I refused. I wanted some fresh tunes, something that would suit the Tamil sensibilities. Essentially, we looked at creating a mass appeal.” Ask him if this is the mass song that Simbu is to croon and he remains tightlipped, saying that he wants it to be a surprise.
