I thought that this book was very interesting, especially since it was about the lyrics of the songs and not the music. So, even if you dont really like metal music you can still appreciate this book. I am happy to say though that I have many more songs to put on my iPod. There were only a few things I didnt like about this book; I thought that the chapters were a little long for just one song and that the book didnt really tell you what the lyrics to that song were. So, in the beginning of the book when it says to print out the lyrics, do so. But, overall if you like music then you should definitely read this book to help you brush up on your rock history.
