^Oh that's interesting. does that work the same for every chart sales? thanks
I don't think this single will even be close to flavor of life's success.
the flavor of life song was in some drama directed to an audience that are media obsessed, so they will surely buy every song that was in it >_>
Evangelion is famous but I think most of the audience are those anime geeks who will just watch the movie and ignore the music in it. even if they liked it, they'll probably just download it cause the social life they have does not include the latest crap in the media (and a lot of those freak fans hate this mainstream utada dude for being the theme song person

)
example: in america that High School Musical soundtrack is one of the best selling crap right now, thanks to the fans similar to hana dori (????) ones. You never see music selling to the #1 spot from scifi movies/games even if they were famous. =/
the sells will mostly be from people who followed utada for a long time, not because of evangelion "promotion." it's more like utada promoting evangelion than the movie promoting her single >_>
i think her promotions are pretty horrible compared to other artists too. people that aren't interested in her won't be pulled in by some theme song, ramen commercial song, pvs of clips she's promoting, etc. =/ well atleast we know she sells because of her music, not other gimmicks
