Sam Cooke said that for a song to be memorable it had to be simple. His song writing skills are pretty indisputable. He also said I say, as a singer grows older, his conception grows a little deeper, because he lives life and he understands what he is trying to say a little more. And I think this gives. If a singer tries to find out what's happening in life, it gives him a better insight on telling the story of the song he is trying to sing. Maybe some folk singers should take a leaf out of his book. Without getting shot of course.
