Ok... just watched it....
wtf where they thinking? Why the forget did she sing "sharing the world"? The tuning in that song is horrendous. I know its the theme song for the expo, but seriously? They could have just had her sing "the world is mine" or "tell your world" (she has a lot of songs with "world" in it), that was strike one.
strike two, david was COMPLETELY awkward as forget!
strike three, live band... that one deserves 8 face palms and two guns. Sharing your world is an edm song. How do drums and the guitar fit into that? I mean seriously, that was almost as stupid as the hight of the projection, i swear to god she was 3 ft tall.
Tldr, the american television is not ready for vocaloid yet.
