Instruct: Classify Amazon reviews into positive or negative sentiment
Query: clear and simple

I like that there is a track for each subject, although some of them not as clear as i would've wished for. It gives you the perfect tools for writing a song, and most importantly how to get there faster. If you are a beginner, it will give you a solid base, if you are advanced, it gives you a good "review" on how certain chords can give you "that feeling or mood". I would recommend it to anyone..
