i personally hope so too, lol! i mean, i know their style isn't dark like the movie, but i can still see them doing a really dark song. maybe something even better than truth?
i think some people would rather see a rock band do the theme song, since that's what you'd expect with a dark movie like GANTZ, but honestly, i don't mind either way. it's all good for me, lol. because arashi could get a tie-in, regardless.
but maybe by doing the theme song they could show a totally different sound of music or a new image? i think it'd be cool! it's a great opportunity for arashi.
i wouldn't under-estimate them, since their a bit due for an upbeat song anyway after 4 mid-tempo singles
so we'll see what happens! regardless, they will totally have a new single out in early 2011.
