Example Input: I don't know if you can actually call this music. It is truly terrible. However, I love listening to it for some strange music. ... I am not normally a fan of rap music, but I laugh out loud every time I hear some of these songs. These Cash Money guys should be comedians. Except for Juvenile, since I can't understand anything he says, which is also rather funny. Don't buy it for the music, but it for the comedy.
Example Output: Positive

Example Input: I appreciate the books a great deal. They are wonderful tools for improving communication, which is something we all need, and especially when the stakes are high. Great book.
Example Output:
