In part 2 we explore the neuoscience and physchological aspects of music, how it can be used to maniupulate us, and how it can even help with things like dimentia or brain injuries. We look into perfect pitch and the (sort of) opposite - tone deafness, why do certain countries have a lot less tone deaf people? We also discover beat deafness and Pip does a crude experiment on her friend with this condition, to see if there's a relation with tone deafness. Some how we also end up discussing K-Pop and Buffy the Vampire Slayer. Many surprises!
