Universal language aside, music has an incomprehensible way of inhabiting inside us. I was introduced to Dr. Oliver Sacks via my favorite radio program Radiolab last year. He was interviewed in two of its episodes Memory and Forgetting [segment: Clive], and Pop Music [segment: Earworms]
Strongly urge you to check out those two programs, at least those segments. Picked up Sacks’s book not long after and I was inseparable from it till I finished. To get an idea of what to expect in the book, check out this New Yorker piece from 2007.
