Example Input: Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...
Example Output: Negative

Example Input: First of all, don't even bother mentioning Sixty Watt Shaman in the same sentence as Alice and Chains and Soundgarden. Cantrell has more talent in his pinky than Sixty Watt has all together. If you want to check out real Stoner Rock, Kyuss and Queens of The Stone Age are a good start. This album is mediocre at best. Red Colony seems to be the only song I could really get into. Cool album cover though! Maryland must have a really lame Stoner Rock scene, because out here in CA, Sixty Watt Shaman would go unnoticed.
Example Output: Negative

Example Input: JMM has never released a bad album. Many would say this is a comeback album but every couple of years he releases an album with great hits. For some reason, radio hasn't played some of his great songs from his latest albums. "Goes Good With Beer" and "Little Devil" would be great singles to spice up country radio. "Letters From Home" deserves to be single of the year and "Cool" is not far behind. The more I listen to the album, the more I love it.
Example Output:
Positive
