For the past 1 week, I keep listening to this song frequently on Radio. It is a song from Parijatham - "Unnai Kandane". It is a beautiful soft song. This is the Bhagyaraj's film in which her daughter is acting. Music is by someone called Dharan. I haven't heard of him before, but has done a great job in this song. This song seems to be set in minor scale. Lots of harmonies are added in the female portions and that elevates the song. It has been sung by Haricharan (Remember Thottu Thottu Ennai?) and Shruthi. I don't which shruthi is this, but at first the voice seemed like Bhavatharini. Don't forget to listen to that song in the link above and post your comments on the song.
