Well, just finished the book, and I thought it was lightweight, really lightweight. Some of his interpretations are so obviously badly wrong; he misses out information that most of us on here would know; he skims over songs that deserve greater analysis; the early part of the book is lifted from his earlier books with no changes, as far as I can see. In summary, most people here could do a better job than Rogan's book. My advice - don't waste your money.
