Suresh,
Me too enjoying NL songs. But I liked NK songs 1% more than NL :D
The themes of these two movies are completely different. NL songs are to do more with human emotions... Like, yearning for mother's affection... But NK songs are slightly different from this... It is more of spiritual, search of god, self realisation etc etc....
But as the movies release, I'm sure NL bgm will have more value than NK's...
Just cant wait for the release...
