Michael here. On first listen I am loving this music. It sounds very big: orchestral and bombastic with a cool electronic and tribal twist. And I love the way he layers the vocals into the tracks.To me it seems like it will be as memorable as anything Horner has done. Music is so important to Cameron's movies, and with the years Horner has been working on this I am sure I will listen to it on repeat just like Braveheart, Aliens, Titanic, etc.
