In search of one particular song - Need Help

[NeofelisNebulosa]

Hi there pals,
after just having watched Ghost in the Shell, I remembered one song whose video looked like it was taken from said movie. I remember having seen it on MTV and such, so it is no AMV but an official song. Must have been around 2007 or so, plus/minus some years (not a good help, I know).
The whole video is a woman fighting some mecha-tank but I for hell's sake can't remember neither the title nor enough accurate lyrics to find it (has something to do with "This is my [fortress/place/ground] ..."), but now that I think of it, I just want to find that song again.

So, if anyone by chance knows what I am talking about and may help, ... do so!

Thanks

I am off to torture my memories into submission

Hah, found it: King of my Castle from Wamdue Project in the year 1999 (so for for 2007 plus/minus some years, ... no wonder I had such problems remembering it).
And no wonder I always had the word fortress in my mind when thinking (castle/threshold -> fortress), I think that is acceptable after twelve years when at the time I was just eleven years old although the rest of the lyrics as I thought they'd be was utterly wrong. Hah, ... and I thought I would have reasons to distrust my otherwise excellent memory.

I am happy right now, as my mind had once again tested time and won!
