Example Input: To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.
Example Output: Negative

Example Input: I was impressed with speed of delivery, condition of product & quality of packaging for the product.The soundtrack itself is wonderful as I saw the original movie when it came out and feel Madonna & Antonio deserved a better review than they got for their performances.
Example Output: Positive

Example Input: I was very happy with my Sansa View, until all of a sudden my micro SD chip was missing. I couldn't imagine someone stealing just a chip, but then when I tried to put a new one in, I noticed it would only be installed for a second or two before the spring inside the unit would expel the chip. It would actually launch it up 4-6 inches! So now I know my original chip is somewhere at the gym, certainly vacuumed up by now.It's a great player, but check to make sure your SD card doesn't come out too easily or just send it back!
Example Output:
Negative
