Singers: Sreedhar Hariharan
              Madhura Dhara Talluri

Lyrics: Vivek

The song opens with impressive flute music and Unakaga song starts to flow from the first note. The tune of the song gets more melodious from one phase to the next and hence Unakaga is a soothing soundtrack. Lyrics penned by Vivek has love inducted in every phrase and AR Rahman's music has highlighted the same. Madhura has added classical music shades to her lines, and the veena music which plays at the background is a perfect match. The song is one complete melodious package of soulful music, a signature AR Rahman romantic musical.
