I like to point KVM's contribs in composing many great melodies - classical as well as light songs. I'll take some of his famous movies and post my comments. Quickly first: 'Sruti Layalu'. Has one of my favorite song: 'inniraasulaunikki'. Beautiful tune in the raga Malaymarutham and sung nicely by SPB & VJ. In this movie, there's a climax song where KVM has composed with a sruti bedham. This is probably the first time this has attempted in film song. more later..
