The World in Six Songs: How the Musical Brain Created Human Nature

The World in Six Songs was one of the most frustrating books I've read in a while.  Daniel J. Levitn's theory (that all music falls into six types of song - friendship, joy, comfort, knowledge, religion, or love) was fascinating, and as a musician and scientist he has the knowledge to back that up.  However, every time I became engrossed in his explanation, he'd awkwardly name-drop or tell a story that just seemed too pat (or included an obvious fact-checking error - "We Built This City" was recorded in 1985 so it couldn't be on a 1970 playlist).  Interesting material, and a lot of potential, but not well executed.
