There's a reason that we humans have been making music for millennia -- because most of us really like it. Our brains respond to music positively, and in turn, we feel good when we listen to it. But a recent study published in the journal Current Biology shows that some people -- in fact, 2% of the population -- don't feel anything when listening to music. Researchers refer to this newly described condition as "specific musical anhedonia."

Dr. Robert Zatorre, a neuroscientist at the Montreal Neurological Institute at McGill University, was involved in the study, "Dissociation Between Musical And Monetary Reward Responses In Specific Musical Anhedonia," which asked groups of students at the University of Barcelona various questions about their response to music. In a conversation with Soundcheck host John Schaefer, Zatorre explains the project, how the condition differs from amusia, and why music might not have an impact on some brains.
