In this task, you are given music product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
One example: The Bee Gees-Their Greatest Hits . Fabulous-This is a must have for any Bee Gee fans. My 4 year old daughter even likes this music
Solution is here: POS
Explanation: The overall sentiment of the review is positive as the reviewer refers to the music piece with positive expressions such as 'must have', 'likes' etc. Hence, the label is 'POS'.

Now, solve this: Marvellous fun and great singing . I have to say that I prefer Handel's Tamerlano for musical reasons. However, Vivaldi's opera on the same subject is very enjoyable and entertaining. Like it has been said of the operas of Haydn, Vivaldi's operas are not great operas, but they do contain great music. Europa Galante, directed from the 1st violin by Fabio Biondi, is in great form and I've never heard them play better. I have their older recording of Handel's opera Poro, and I enjoyed that one, too. The singers here are an excellent ensemble. I like the dark and expressive voice of Ildebrando D'Arcangelo - he was also marvellous as Leporello in Gardiner's Don Giovanni. David Daniels is fantastic, as usual, and he is possibly the best operatic countertenor in the world at the moment. Patrizia Ciofi is best heard and not seen - sweet voice coming from a madwoman (check out the DVD!). Vivica Genaux has been hyped to within a centimetre of her life recently. She has a nice flexible mezzo voice. A little too much vibrato for my tastes and she looks like a chipmunk when she attacks coloratura passages. Marijana Mijanovic sings well - she was excellent as the neurotic Penelope in the Christie / L.A.F. DVD of Monteverdi's Il Ritorno d'Ulisse in patria. She is alarmingly thin - possible health problems? She doesn't engage with the conductor or orchestra at all in the DVD - the only singer who doesn't. Elina Garanca looks beautiful (and healthy!) and sings beautifully. She has a lovely contralto voice. I hope I see and hear more from this artist in the future. I am not a big fan of Vivaldi's operas - I enjoy them as collections of arias. I wonder how well Bajazet worked on stage? I'd love to have a DVD of this production, I would like to see how a Vivaldi opera works on stage. Vivaldi's operas don't have imaginative scorings and the orchestral passages are fairly prosaic. A lot of what goes on in the Vivaldi operas I've heard (I have a few in my CD collection) is pretty routine. However, I am open minded on the subject and I would like to see how well a Vivaldi opera works on stage.
Solution:
