What is it about the way some amazing people sing that gives us goosebumps?

Inspired by this

I assume everyone gets the same physical reaction of goosebumps when you hear a voice hit a particular pitch (or whatever it is) perfectly. Do you think it’s some instinctive reaction to a certain sound that goes way back in our evolution or something? What reason would we have for having that reaction? (While I’m on the subject, when my full blood German shepherd howls, which is not very often, it gives me the goose bumps too. It’s so wild and mournful that it makes me shiver. I wonder if it’s related to this in anyway….?)
