Sounds to me you're asking the unsolveble question of "what is art and where does it come from".
When people hear music, it tends brings out thet same emotion from me than the person next to me, it is interperated by our experiences, memories,
perception etc etc. Yes, esspecialy with music, primary emotions are easily brought forward (such as anger, sadness, etc) but they tend to relate to a
certain memory of some sorts. Most of the time we are unaware of this, but a simple way of testing is just to look back at who you tended to listen
too last winter, and then who you listened to this summer, and do that to the year previous, many times (for people who listen to music, and not just
dance/get drunk to it) the same bands tend to pop up in certain seasons.
For me as an example, in summer/sunny warm weather, i tend to listen to more up-beat, happy music (such as ska, indie, regge, trance etc) but in the
winter, i tend to listen to more darker, heavier music (industrial, heavy metal, prog).
I could go on forever with this example, but to cut it short, people tend to have happier memories in the summer, many from childhood in the summer
holidays from school, family holidays are typicaly taken in the summer, those lounge days in the park with some friends when you where teenagers.
There are also chemicals released with sunshine that boost your mood. Because of this, music with higher frequencies (and major notes) tend to relate
to us with happy emotions.
Winter on the other hand, is dark and cold and missreble. It's too wet to go outside and play when you were young, less sunshine (the chemical thingy
again) and so on. So people tend to be more missreble in the winter (well, after xmas anywho, another reason why all xmas songs tend to use high notes
(major) rarther that low (minor notes for you music folk).
Take a quick look at the charts over a 12 month period, you will notice how in the summer time it's all happy go lucky cheese, where as in winter its
all slow, "somebody left me and im all alone crying" love songs.
Sorry if i woffled on for too long, music is a major interest of mine
