Example Input: Considering how much bad music is out there these days, this was nice to come across. Covers a wide range of topics and moods, musicianship is pretty good. I'd recommend it to just about anyone. My tastes are usually heavier and more progressive - Rush, Dream Theater, Iron Maiden, Queensryche. But I like this disc too.
Example Output: Positive

Example Input: My husband and I were not able to attend a birthing class, so the doctor suggested we rent/buy a video. We decided on this one, and although the 'teacher' was a bit corny it was helpful. I especially liked that you could fast forward and skip parts! All in all it was a worthwhile purchase and proved helpful to us both.
Example Output: Positive

Example Input: diseased yellow pile of tortured meat, that's what it is. I used to eat it... but than I found out how it's made, that's just gross. people are disgusting and will eat raccoon's a* on a stick if it's called a delicacy.
Example Output:
Negative
