Now I love soundtracks and scores, I own hundreds of them. But upon seeing Charlie and Chocolate Factory I think that this soundtrack is by far the best in a long LONG time. Energy and everything Elfman brings to this is just amazing and he far outdoes himself. I just got this and am listening to it after about a week of seeing the movie and the music still holds up, so its not a fluke. The music is just awesome, oh and Elfman did ALL the vocals, ALL OF THEM, lets see Williams or Zimmer do that.
Now my favorites of late have been Kingdom of Heaven and Batman Begins, but I think Charlie and the Chocolate Factory just outdoes everything. And if you don't like this soundtrack, then you are either a terrorist or a penguin.
EDIT: I will admit that the rest of the soundtrack is at times Elfman-esque, but that is quickly brushed aside when one hears the new Ompa Lumpa songs in all the glory. It is best to actually see the movie first, but this is one Elfman soundtrack that has really stood out from the rest. Spiderman has a unique theme, but that is all.
