Right, Personality has many different ways of changing even in people that were brought up the exact same way in every way.

I don't see how they would have separate personalities if they had the exact same DNA, were exposed to the exact same things, and lived in the exact same manner.
The music would be different, but only because there are too many external factors to account for, like you said, food between the teeth, actual differences in food, maybe one fell off the bed in the middle of the night, and who knows how the human brain develops(despite identical DNA). You're asking for too exact of a match for an unbelievable amount of variables.
A bit simpler scenario, Take that same question, and apply it to two of your AIs SYG. Two AIs, created with the same memories, the same capacities for learning, and the same sized memory. They are both systematically fed the same exact data, then asked to respond to a series of questions about how they feel, will they both answer all the questions in the same way?
Of course the human brain is more complex in so far as we don't understand how exactly it works yet. You should ask a question that is a little more gray, something that is not so exact. Let's take the same two kids and paint both rooms red. What do you think their favorite color will be when they grow up? Red? Will it be the gray robot because he's different? Regardless, the important question is: Do they both have the same favorite color? Try feeding them the same thing 3 times a week, and anything else(but nothing of the same) for the other 4 days. That is, 3 days of the week they get the same meal, but the other four meals can be anything, just not the same thing. Would they both grow up liking the same food?
DNA is responsible for differences in people and personality, but even more so is our environment.
