Example Input: Although the music of this CD was just what I needed to teach a lesson on early jazz and it's influence on the artist, Mondrian, I was disappointed that it did not have the cover sheet shown or any information about the artists. The CD package was broken.....Other than that, it was fun to play it as the children in my art class painted their own version of"Boogie Woogie Broadway" by Mondrian.Art Specialist --- Las Vegas, Nevada
Example Output: Positive

Example Input: I work at a Wild Birds Unlimited store and customers rely on you to give them the best information on bird feeding and care available. This book is super helpful in achieving that goal.
