The thing is, I really shouldn't have asked you guys. That was problem. I should have went and asked some dude with a PhD is Psychology.
Wtf would they be able to tell you about music taste?
What happens in someones brain when they hear a song they dig?
All sorts of reactions get stimulated, but again it's entirely down to the individual. Our brains all work in different ways, otherwise we would all like the same stuff.
And why do many people like one song vs another?
We've already answered this, repeatedly.
