Scientists and music professors at Cambridge University came together to find a song that introduces the strongest fight or flight reaction of any song. They went through thousands and thousands of musical pieces and composers and tested these songs on hundreds of different people. After 7 years of research and observation, they finally found a song which made 94.7% of listeners surge with adrenaline, so much so that the riot that ensued caused billions of dollars worth of damages to the surrounding area.
