I'm with you on these views castleberry,
I would add some personal views too:
There are people that feels that internal rithms more than others but all of us own this skill. This point is well prooved by the fact that almost 100% of us like music and react unconsciously or not to it.
Every one has it's own preferences and different responses to the different music combinations they are exposed to. Cultural context and genetic patterns constantly sculps the individual musical perception as a whole.
Culture as a context is definetely a major factor on what we are .
