This Is Your Brain on Music, are leading me to view the good old question, "What have you been listening to lately?" in what feels like all new ways. In a world where all taste is equal, there may be no taste at all, replaced only by interpersonal connection and alliances, which are affirmed by the music (and other connecting points) in a feedback loop, or "virtuous cycle." The more you like your friends the more you like the music you share—and more importantly, the sharing. That's all it is. This is at once terrifying and exhilarating to anyone with a stake in the critical enterprise, which I think is finally the great big kick of Wilson's book. Really, it's one not to be missed.
In case it's not at the library.
