Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not what I expected.....

I thought this was gonna be more like the Popoff books....in depth reviews of the albums, so you get an idea of what is good and what to avoid. Instead, all you get is lengthy narratives only describing band member changes and album releases, and each band gets a discography. If you really care about Guitarist X replacing Guitarist Y, who then went on to form Band Z, then get this book. If you're trying to get an idea of what the bands sound like or which are the best albums, this won't tell you.
