Example Input: The best of all . I have heard several Bohemes in my time - my favorites being the versions with Pav and Freni; Tebaldi and Bergonzi; and this one. Neither of the first two can match this recording in overall effect. Karajan with Pav/Freni, while firmly in possession of his own wonder, misses by a hair Beecham's sensuous conducting logic. Also Pav is not the best Rodolfo: he sings too opulently to convey a blue, starving poet. The Tebaldi/Bergonzi set is a sure contender, and might have stood right with this one if its sound weren't so bad.         Now as for this set itself - three words say it: Bjoerling with Beecham. These were two of the finest artists of the last century, and it is a blessing to have this record of their collaboration. Jussi, while perhaps not as romantic as Bergonzi, was a Rodolfo for all time. That ringing golden tenor truly could build castles in air. And hell, he was romantic enough for comfort. Add Beecham, and, if you please, you've got glory. His pacing is perfect. Just listen to about midway through "che gelida manina," where Bjoerling soars and Beecham expands the tempo to let Jussi's voice raise the rafters and burn deep. And I tell you what, Jussi could burn. The quantity of air that man had was astonishing at the least, and he didn't waste it: his phrases are easy, well-drawn, and thrilling.        I have no important complaints about anyone else in the cast. I actually prefer de Los Angeles's Mimi, though I think she sometimes doesn't support high notes with enough air. As for the orchestra, there are a few mishaps where accurate entrances with the singers are concerned, but that is hardly surprising - the ensemble was assembled in roughly two days and its memebers had barely played with one another or with Beecham. The sound of the set isn't as good as one might expect from the Great Recordings series, but it is acceptable, and a well-informed ear can fill in any lacking overtones.    Buy it. You'll love it for many years, and then pass down through your family
Example Output: POS

Example Input: It's Just a Mess... . I disagree with the spotlight reviewer's assertion that this movie-musical was overproduced; it seems more to suffer from Spartan-like efforts in production.  I did enjoy the fact that part of Oz was in an urban setting (i.e., the subway station), but it looked like they didn't even try to clean it up a little.  But enough about the movie, this is the soundtrack...and as I stated above, it's a mess.  This classification mainly rests on the shoulders our "Diva Supreme" Diana Ross.  Stephanie Mills set the bar high, and Miss Ross did not even come CLOSE to that standard.  She was a visible, vocal and emotional failure.  Her renditions of "Be a Lion" and Home" (my favorite two songs} were dreadful--in the latter she even sang incorrect lyrics.  She just does not have the talent or ability to effectively communicate Dorothy's character, let alone sing her songs right.  I would rate this with ZERO stars if it were at all possible.  However, the two stars are earned by the members of the original cast (especially Mabel King) and one addition: Ms. Lena Calhoune Horne.  She was radiant in voice and appearance and brought the level of inspiration and power up a notch as she belted out "Believe in Yourself".  They alone save this movie and album from just being a total misstep.  Yet, we still have Diana Ross here absolutely slaughtering the vocals and pathos of Dorothy, so all-in-all it's just a mess
Example Output: NEG

Example Input: undeniable pop masterpiece . _blue_ is simply a masterpiece of pop-rock music! it has tons of massive hooks, sweet grooves, incredible melodies, awesome vocals courtesy of mr. jenkins, and dashes of experimentalism! the melodies soar overhead with his sweet falsetto voice, the drums rip and roar through some funky bass grooves, and the guitars strum delicately or spit out a distorted lullaby of happiness. as much as i enjoy third eye blind's eponymous debut album (which is one of my favorite pop albums ever), i think _blue_ is even better. it is impossible to deny the songsmanship on display here. everyone should listen to this album
Example Output:
POS
