Music is the most neglected science yet most influential to the society

Music can add or subtract goodness to a person. (I forgot the links but in psychology, music can heal people. In medicine, music can improve brain function {babies inside the mother thing}).

also you can tell a persons attitude and outlook in life if you know his/her music playlist ^^
Music can be so powerful it can affect your mood, brainwaves, and even your heartbeat! It turns out that when we listen to music our body reacts to the sounds we hear.If a person listens to rock or techno, their heartbeat will involuntarily speed up. The opposite is true if someone listens to more calming or instrumental music.Music is so influential it can alter your heartbeat, pulse rate, blood pressure, decrease your muscle tension, and even affect your body movement and coordination!
