Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I had high expectations for this player. I have the Sandisk m240 and m250 and they have amazing sound quality so I thought, being from Sandisk, it would follow suit. It didn't. Very disappointed with the sound quality. It even breaks up. And forget about organizing you music and videos. You can't create folders on your own. Have to use Windows Media Player. And I still haven't figured out how to make video playlists. WMP won't accept mp4 files in the Video playlist. Plus, when scrolling through your library, the scroll wheel only goes forward so, if you want to play a song that begins with "Y" and don't what to start from "A" and scroll through 8GB WORTH OF SONGS all the way down to "Y" but want to scroll up from "Z" to "Y", you can't.
Solution: Negative
