Task: Sentiment Analysis
Input (English): Review: Before you buy this thing, understand one thing. When you mark a song, you have to remember the station you were listening to at that time. So if you have 10 emarks, you have to remember the station you were listening to at the time of each of the emarks. I wondered about this detail before I bought the thing and found no mention of it anywhere on their website. I assumed it would mark the station somehow. My mistake. Learn from it. 
 Polarity: Negative
Output (English): True
