Venkkiram,
While listening to Ennodu Nee Irundhal, did it cross you to refer to Elton John's piano Solos. I recomend his 'The Lion King' (Broadway) Musical (Esp. Can you feel the love tonight) [or a "Candle in the Wind"]. Also, if you are interested to take a walk around the Opera world (yes the one where trees sing too), I recoment 1986 Phanthom of Opera Musical. Two song should interest us wrt Ennodu Nee Irundhal - "The Point of No Return" and "Wishing You Were Somehow Here Again".
What ARR has brought is an altogether new form of taste to TFI audience. Anyone not quite used to Ballroom or Operas, for that Broadway theatre musicals will find it quite difficult to understand this song. Please listen to the above mentioned songs, Ennodu Nee Irunthal will make us proud. Like I mentioned earlier, ARR has shined a lot in this song, and sure it will get noticed and mentioned internationally.
