Q: Review: I bought this CD originally when I was in junior high, to accompany me while I practiced my saxophone (I preferred to practice to Beach Boys music over the school fight song). Anyway, it's also good for karaoke. However, be careful listening to the previous reviewer, who either can't count or has a different CD. There are 15 tracks on the CD, which last I checked is *not* over 20. 
 Polarity: Negative

A: False

Q: Review: This book did not help me with my economics class. Even though I passed the course with a B. This book reads more like a novel and really does not simplify economics at all. I work better with definitions and examples and this book gives none. 
 Polarity: Positive

A: False

Q: Review: My experience: I got this from FM, not Amazon. The DVD player rattled pretty loudly sometimes (but not always) when I put in a DVD. I tried several. The picture quality wasn't all that great and the screen got a horizontal line thru the middle after a short time that would not go away. Plus one of the other reviewers was dead on about the remote - the layout makes no sense at all! Very poor human engineering, IMO. I brought it back to the store for a refund. I saw the same model under the Emerson name for <$400 at WM but was hesitant to buy it.
