I must admit when I was reffering to the stuff I play on the banjo, I was meaning dance music so there are no words to consider.I guess with songs, matters can vary a lot more. How about a shanty? I'd still rate rythm as more important than melody or words. Maybe, in that order, 50, 40, 10. Then how about a ballad? I think words matter the most and a strict rythm could kill the song...
