A BBC article reports on people who experience music as an almost sexual pleasure.
The article also observes how idiosyncratic the response is. The author uses an Adele song (whoever she is) as an example of particularly evocative dissonances, but when I eagerly went to listen to it, I found it didn't do a thing for me. Then, something like "Women of Ireland" that tears my heart out of my chest leaves someone else cold. And there's the enduring mystery of why I've been completely indifferent to every Mozart piece I've ever heard, when there may be no other composer so universally beloved. Why can't I hear it? The reaction either happens or it doesn't; there's no explaining it.
