Batman Arkham City - The Album. To be honest, I only got it for Mercenary, but I really enjoyed the entire CD. Only some of the songs seemed like they fit with Batman, though....
Also, a Kalafina CD...Amazon says it's called: Kagayaku Sora no Seijaku ni wa (which I think is actually wrong, because the BB wikia is calling it
something else...you know what, I bought and am listening to this:
Link ...why didn't I think of that sooner? >_<) Anyway. Despite my short comings with language barriers, it's a very pretty CD. ^^ There's two versions of the title song (one's an instrumental) and the third is one I'd never listened to before. I liked them a lot. ^^
