Only listened to the first disc so far, and I have mixed feelings. The songs are pretty good, mainly because of the hooks (most of which were present in the trailer video), but the lyrics are absolutely horrendous. It's a damn shame, because some of the subjects have a lot of potential (E-Police, Pink Beatles, and Parental Procreation Permit) but they're quickly nullified by the lyrics.
That said, that was only my first listen, so we'll see how it grows on me.
