If there's one thing you have to say about this album, it's that it's very varied. There are many different types of music on the album, from straight rock similar to Every Six Seconds to more poppy music similar to Back Into Your System. Some of it is even reminiscent of their first self-titled album, Saliva.However, I can't give the album five stars on principle. I agree with other reviewers in that Black Sheep sounds EXACTLY like Animals by Nickelback, if only a little slower. Not cool guys, not cool.Other than that, a great album you should enjoy if you like Back Into Your System and Survival of the Sickest.
