Music is something that seems to affect us on a subconscious level. There are a couple studies on why this is so but many give vague answers. I guess we are just hardwired to respond to music stimuli stronger than other species. Wish I could give a detailed answer but like I said there is not a whole lot of actual evidence as for why music effects us. I ain't no scientist bro.
