People have to realize the reason behind them sounding so different on this album is because they have only one original member, and mostly new members since the last album. I love the new direction personally, it's thoroughly entertaining and fun to listen to.
Also, these guys really do bring meaning to the "I'm huge in Japan" idiom, albeit in a less filthy way. They're like superstars over there, and obscure here. I imagine not for much longer though. :)
This. This sooooo much.
