I posted this here rather than the behavioral Sciences forum because I want a genetic answer.
Music Makes us Laugh and sometimes Sad, Songs/Chants/Music have been used to raise soldier morales through most of human history which shows some evidence that music affects us profoundly.
Maybe we respond to music because of our love for order, we relate that to sounds we hear and then music is created, but does that explain why we feel certain emotions after hearing certain musical performances?
