What Happens in the Brain When Music Causes Chills?

According to a recent article in Smithsonian Magazine, "The brains of people who get chills when the right song comes on are wired differently than others."

Many different genres of music cause me chills……..Bach’s “Sheep May Safely Graze;” Andrew Lloyd Webber’s “Pie Jesu;” Handel’s “Xerxes;” and then “Whiter Shade of Pale,” “I Wanna Hold Your Hand,” “Hotel California.”  Add some Christmas music like “In the Bleak Midwinter,” and “Wexford Carol.”  And I haven’t even begun with the old timey music and gospel and hymns. 

What music gives you chills?
