Example Input: I did not know this was the audio cd of the game, I thought it could be used on the playstation. Maybe the other guys are from the US or somewhere where it is actually easy to get the game,and play it,but this was all in japanese and was not compatible with my machine. I am deeply disappointed as i love the arcade game, but the Dance stage euromix (Dance Dance Revolution equivalent) is lacking in decent tracks, many are jungle-y and are difficult to dance to them. Also, most of these tracks are unheard of here and are therefore not very enjoyable. However, my favourite are Keep on moving, make a Jam, and Video Killed the Radio star. But it gets a bit pedantic if you keep playing on these tracks. If anyone is in the same situation as I am, or those of you who are lucky enough the play on the newest version, can you please let me know where I can order one? I am in dance deprivation/boredom!
Example Output: Negative

Example Input: I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.
Example Output: Positive

Example Input: The cover fits reasonably well, with only slight shifting. It does not obstruct any of the controls, display, the mouthpiece or the earpiece. I really like the clip on the back. I'm pretty satisfied overall.
Example Output:
Positive
