I'd previously read and enjoyed 'This is Your Brain on Music' by the same author so it seemed natural to buy this one too. A quick flick through the index told me that there were contributions by Frank Zappa and Joni Mitchell - so all the signs were good. For some reason, however, I put off buying it for some time (until I got in cheap on E-bay actually). I have to say that I'm pleased I did: I'd have hated to pay full price for such a disappointing book.
It seems as though the author feels he has to remind us on every other page about how "Natural selection has favoured those who were able to... etc. etc." Okay, so it is the point of the book but it can still become tedious after a while. When somebody persistently tries to shoehorn everything into one system then the result can start to resemble superstition. My impression was that the author could have made the book half as long and it would have been twice as good. There are occasional nuggets in the book but these are few and far between. Unlike another reviewer, I actually enjoyed reading the song lyrics: they provided a welcome break from the proselytizing. Oh, and nitpicking it may be but there were more than a few typos scattered throughout the text.
