This Will Send Chills Down your Spine

Autonomous sensory meridian response (ASMR) is used to describe a pleasant tingling sensation in the head, scalp, back, or peripheral regions of the body in response to visual, auditory, tactile, olfactory, or cognitive stimuli. 

There is strong anecdotal evidence to support the phenomenon but little or no scientific explanation or verified data. For an example of this experience watch the video posted below with headphones on.
