Instructions: 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.
Input: Great, but a step back . This is a solid rock album. But it's not as good as their previous effort "Spiritual Machines". The sound has more bottom to it (thanks to Bob Rock -- or no thanks?) but at the same time it isn't heavier, which is strange. At first I was very disappointed with the album (I have all their previous recordings), but it eventually grew on me. However, if this is a new direction for the band, I don't know if I like where it's going
Output:
POS
