Hi Prasad
It doesn't work that way. Even if its a hit, sales of audio cds are practically negligible today. This is true even for big bollywood films. Today audio cds are mainly made to give away as complimentaries to the stars and others involved with the movie. Nobody bothers with the sales. Even if you sell 2000 cds you are going to make a profit of about only Rs 40000. With that sale comes excise, sales tax and other formalities, all of which need to be met. Its simply not worth the time or effort.
And thanks for the compliments about the production values for the movie.
