Example Input: "What is this.....?" . O.K. When I heard that Dave was going to remaster/re-release the Megadeth back catalog I got real excited. I still believe that this album is a true masterpiece, but when I bought the 2004 remaster/remixed version I was MORTIFIED!!!! What was Dave thinking when he decided to remix it. All it needed was to be beefed up just a little, but he went to great extremes to ruin it. I know Megadeth fans were pretty pissed about this, but the one thing I did remember is that the first time I heard Countdown... when it was release in 1992 it gave me chills........period! I have regrets about buying all the remasters at once.......BIG MISTAKE!!! So in closing I went back and found the original versions of So Far...So Good...So What!, Rust in Peace, and of course Countdown to Extinction, and yes Capitol Punishment...The Megadeth Years. I'm glad that I was able to locate them
Example Output: NEG

Example Input: Buy the book and the CD! . This is a must-have CD for any parent who likes introducing the simple joys of great music to their kids.  My mom and dad (both in their late sixties) enjoy listening, too, and my child can ask her grandmother about other songs from "back in the day."      Get the book, too!  Nicky's really big personality shines through as he rubs elbows, er-paws, with some jazz heavy-hitters.  Your child will love the photos and will also discover some great new vocabulary words like bop-a-re-bop. The CD and book have proven to be a great gift combo.      Take a listen and enjoy!
Example Output: POS

Example Input: Old, but new . I enjoyed this album. At first glance it appears that it is your standard post-1990's rock album. But after a good listen, you realize that they have succeeded in forging a rather good and unique album. It's well done and has a good shelf life due to its distinctive sound
Example Output:
POS
