Input: Consider Input: I've read all of the Night World books, and this is a great book, but I must say, it's not L. J. Smith's best

Output: Positive

Input: Consider Input: I recall this recording on LP in the early fifties. It conveys the humour and genius of Mozart with great singers although other than Steber they were not previously identified with WM.

Output: Positive

Input: Consider Input: I thought this product would be great, and help out my kids a lot!! My daughter hates it and it is so confusing. We can't find a lot of just regular songs. It is easier just to call the radio station and find out yourself.
Output: Negative
