Good to know that the BGM makes a return (yay!); I guess the variation of Hedgehog's Dilemma or maybe it's the new song that played during Rei's "Emergency call. I'll go on ahead." because I heard those piano elements in that clip. I just hope we do get some mostly unused S2 Works stuff. :(
What sounds like some J-pop background supermarket music
*crosses fingers* "You are the only one, kitto, anata dake..." or "Shinjitara nanimo kowakunai. Aoi Miagi ga..."
Oh and in before the whoring of Rebuild by Gainax/Khara:
Rebuild of Evangelion 01 OST: You are (not) alone. And sure you've heard most of these songs, but that's never stopped us before, right?
