Music is one of the oldest forms of entertainment, but it is also so much more than that. Since the dawn of man, there has been some kind of music, and most of the time it has been a direct extension of humans, just like talking, or walking. Everyone likes some kind of music, or at least some songs. And just like humans themselves, music tastes are truly unique to each and every human being, because no two people like every single song the other likes. You could literally create and identification on a person just by knowing which songs they like if you had time to create the data base.
Music is a part of everyone. We prove it, every time we tap our toes to a song. Rather you're a musicians or not, I believe we are genetically programmed to love music
