Query: Mostly disappointing

I'm familiar with at least half the artists and the albums and the stories this book tells about. Not much is accurate. The writer gives too many personal opinions on the music, many discographies lack important information, the selected sample lists are unnecessary (and take up LOTS of space in the book)(...). Lots of research must've been done in order to get this much "fact" into these many pages, but obviously not enough. Not recommended.
