They went in a completely other direction starting with FUZZ... Which, I really like that song, and a few others off of Shion. But now their music is starting to lack what made them awesome, and I don't think the last album is as good as it should be because MUCC doesn't work nearly as well with the type of music they're trying to do now.. The only song I liked off of Kyuutai is AGEHA, and I don't like the new singles at all.
I'll still follow them, but I wish they'd put out another Isho or Waga, Arubeki Basho! Heavy rock and metal is what they do best, of course. It just fits, and they're so perfect like that. Or, if they must be so poppy, at least make it amazing, like Horizont. *_* Because, even though that song isn't very MUCC-ish, it still has the awesome flare a lot of their older stuff had. (They really rock all of Gokusai, even though it isn't the usually heavy stuff. :O)
