Good Review

At first listen, I was not at all impressed. Although it's a catchy beat, the lyrics are cliche and some of them pretty inappropriate. But then another album comes along and my opinion changes. And that's what this is. Not nearly as impressive in production quality but still better than most music out there, and that's why it earns its keeps. Good job, Linkin Park!Update:Now that I've had more listens though, I'm impressed with it.
Bad review

this books is okay,but not good enough for 4 or 5 star.
