I got chills when Thorin started to sing. And the song actually was in the book. What I really, really hope for, is that when Bilbo and the dwarves get captured by the goblins, that there will be something along the lines of the song "Down to Goblintown" that was in the old Hobbit animated movie from the 70s. I can't really remember if that song was in the book or not.
I cannot wait until this time next year. Why oh why did it have to be a year away?! And then we have to wait yet another damn year after that to watch the 2nd half.
