Music director Vivek Sagar of 'Pelli Choopulu', 'Sammohanam' and 'Brochevarevarura' fame is upset with Vishwak Sen's recent tribute to NTR. On May 20, marking the birthday of the 'Aravindha Sametha' and 'RRR' actor, Vishwak Sen (the actor of 'Falaknuma Das' and 'HIT') came out with a rap song to pay a musical tribute to NTR. His intentions as a fan of NTR are pure. However, the tune heard in the song was composed by Vivek Sagar for a movie.

Taking to Instagram, the young composer has taken a strong exception to Vivek Sagar's seemingly unauthorized use of his tune. "I am not associated with this video. I have asked you (addressing Vishwak Sen) to get this down and you have failed to do so. You have killed the vibe of the song by making this. As an artist, I am truly disappointed with this attitude," the musician commented on Vivek Sagar's page.

The buzz is that Vivek Sagar wants to follow the legal route to get the rap song off the Internet. He wants to involve Sony Music in this.
