I refreshed that last night so I could find it again today, after a friend told me about a therapist who years ago had patients choose a piece of music and it was used in some way as part of the therapy; after wearing out the original cassette (!) a long time ago she recently decided to get another copy of the same artist and performance, now on CD. However it works, whether placebo effect or something else, she feels a physical response and said that playing that again after all of this time was remarkably soothing. (We're talking in the 1970s or 80s in California's wide-ranging attitudes toward alternative treatments for things, but if it works, it works.)
