If you would like to here any of these bands just pm me. You will not be disapointed, but some of it can get a bit heavy...

I think Explosions in the Sky or Pelican would be cool for blame!

Beneath the Lake; ambient drone. Like a glove!

Hmm, sometimes when I listen to Starlight by Muse or Map of the Problematique by Muse I had visions of the Megastructure in my mind. They're cool songs! And maybe Seu's soundtrack would be Knights of Cydonia by Muse.

nine inch nails!!!!!

things falling apart album suits perfectly

a really awesome japanese industrial band, with a similar aesthetic
the god of noise

though for a lot of it, I'd say the ghost in the shell movie music would work...with its juxtaposition of traditional and new.

Call me crazy, but whenever I read Blame! I get "Passion" by Utada Hikaru stuck in my head... back in the day, it was the only song on my sister's ancient laptop that I was borrowing. And for whatever reason, it just seems to fit the mood sometimes.
