Example Input: "Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.
Example Output: Positive

Example Input: I was surprised to see that the item was used. Advertised as new. Would have liked the new ones stead got used.
Example Output: Negative

Example Input: Certainly this 2nd symphony should have shown the world Raff was a rising star. The opinion of his contemporaries that Raff was one of the greats is borne out here. The 2nd movement is so lyrical, it is worth the price of the disk by itself. The orchestra, though perhaps not well known, gave an outstanding performance. It is a pity that my CD from Amazon contained no program notes unlike what another reviewer reported. However, I'm very pleased with this very fine disk and strongly recommend it to anyone who enjoys hearing Romantic era works that ought to be better known!
Example Output:
Positive
