Teacher: In this task, you are given music product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
Teacher: Now, understand the problem? If you are still confused, see the following example:
The Bee Gees-Their Greatest Hits . Fabulous-This is a must have for any Bee Gee fans. My 4 year old daughter even likes this music
Solution: POS
Reason: The overall sentiment of the review is positive as the reviewer refers to the music piece with positive expressions such as 'must have', 'likes' etc. Hence, the label is 'POS'.

Now, solve this instance: what are these official reviewers thinking? . this not a terrible album, but it is not that good either, and this, when coupled with the fact that there are many other bands doing very similar things much better than knapsack, means that it probably isn't worth the investment. i have never heard any of their other albums, but this one had neither wonderful guitar work nor intriguing vocals, and the lyrics (which have been called brilliant by one of the official reviewers) leave something to be desired. the first time you hear this album, you will probably like it, but after three or four more times all the way through, i think you will probably be either skipping half the songs, taking the album out after three songs, or running to your local used cd store to get some of your poorly invested money back. it just doesn't have that lasting quality that a great album has; this album does not leave you wanting more, as a brilliant album would do. in short, not a terrible album but not worth paying full price for, especially when there are so many bands out their which are doing the whole emo-punk-pop thing much better
