Query: The best of thier albums thus far.

Don't listen to those who have given reviews saying "Slipknot sucks, they aren't metal, yadda yadda, listen to real metal, yadda yadda." Slipknot is still a developing band and they are not your conventional metal. They are different, so don't say that something sucks because you don't know what you just heard. To me a good band is a band that can produce something you have never heard before, something unconventional and that is what Slipknot is. If you ever hear their actual first album Mate. Feed. Kill. Repeat. you really see what they came from and it has changed significantly. This hard and angry music. Enjoy it...
