...there are... too many versions =.=;;
There's no way on earth I can find the version I like ;o;
Although... from your choices, it looks like you like... uber techno stuff with robatica lyrics meshed with electronica.
I just like kind of... dream trance type / symphony ._.;;
THough that 3rd video was quite appealing to my taste ^o^~~
and that last one as well.
and the Obligatory U.N.オーエンは彼女なのか？ is a favorite classic of mine
. Very... symphony like.
Maybe you can tell what kind of genre I prefer...?
