I would vote for Lulu if I could call it a metal album. I wouldn't call Korn or Limp Bizkit metal either. If I had to choose the worst metal album I heard all year, and I'm not going to get many supporters here, it's Machine Head. But hey, Machine Head has never really been my thing, and at least I gave it a couple good listens.
I love inside jokes, I'd love to be a part of one some day.
