The song was rendered by Shiva Naagulu but it was replaced in the movie. Devi Sri Prasad had sung the song in the film and it looked very odd in the theater. And in the recent media interaction, Shiva Nagulu said that the makers have replaced my voice in the film with DSP. They could have informed me one word regarding vocal replacement.
He further added, DSP heaped praised during the pre-release event, and he finally made my efforts waste. And it is learnt that the makers have changed the Aa Gattununtaava’ song with other singer and replaced it in the film as well.
