Input: Consider Input: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

Output: Negative


Input: Consider Input: The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires.

Output: Negative


Input: Consider Input: Let me first say I'm into HipHop(real Hiphop, slug, Atmosphere, etc). I have latelly been checking out the Euro scene of music(I don't know bought a Bmw could have been influencing me lol). I like this chick(not only cute) but she is cute and beats are catchy. Their music makes wanna make me drive fast. The older I get(30), the more I listen to beat and the complete way the music is put together. So liking the Goldfrapp stuff. So I by these cd's for my girl(while secretly ripping them to my zune). Right now working overtime to go check out Europe and stuff(not better than America, but different obviously the as an European visiting here. Good catchy cd, interesting use of instruments and keyboards. Did I mention she is cute little thing. Check out their videos they are a trip.


Output: Positive
