Interesting question arkady . . .
I think we all recieve the same stimuli, but have a unique interpretation of it -
I have always wondered why certain rhythms 'feel' the way they do - what is it about 3/4 or 6/8 time that makes them feel so different than 4/4 or 2/4?
Is it a matter of conditioning or do these patterns of pulses connect to some fundamentally different primal elements within our brains?
Likewise, why do major and minor chords convey such different feels?
Why do particular sets of intervals (chords) seem to 'fit' with others?
In the Western cultures, we are conditioned to expect music to use our chromatic (1/2 steps between notes) scales. Other cultures (Middle Eastern, some Asian) use quarter-tone scales which seem very odd to our ears.
I think what all these questions are getting at is "Why is music appealing to human beings?" Why do we seem to need it or want it?
All interesting stuff to ponder . . .
