I'm personally very familiar with the tingling sensation that ASMR describes - having experienced it a lot as a kid, so I was blown away to find a burgeoning online community.  This is a great introduction to the ASMR world with different perspectives from a physiologist to a neuroscientist to a therapist.  I think there are a lot of parallels between the effect that ASMR has on the body and what music to work to can do.
