Unakaga is the song title of third Single of Thalapathy Vijay’s Bigil. Unakaga is a melody track composed by A.R.Rahman 

This song features Thalapathy Vijay and Nayanthara. As we all know Vijay and Nayanthara are joining hands a decade after their previous movie Villu.

On first hearing, this song feels like a soulful melody from A.R.Rahman. Lyric video suggests that it was shot well with the lovely chemistry between the duo. 

This song will surely be another chartbuster song of the album.
