Songs 2 the soul...

There are very few songs that can touch the soul and the heart. To me, these three are the best that fits aptly into this category. In the order that I like, here are those:

Vellai Pookal - I have always thought ARR can sing only songs of high beats but this song in particular has proved me wrong. A song that can rip the hearts apart with its wonderful meaning. It's only available in bits n pieces in the movie

Sutrum Vizhi - A bharathiyar song; Great rendition by Hariharan; A Hariharan - AR.Rehman combo

Uyirum Neeye - Only few years after this song is released, I came to know about it. Another great song and I feel very relaxed and moved when I hear this song (Not sure why?:)) Unni - ARR combo
