I'm always stunned when somebody learns German. I consider German quite dificult for foreign language speakers because of its grammar which consists of more trapfalls than regular rules.
I myself had a hard time with Latin, which is similarly hard to grasp, especially because it's dead, haha.
Anyway: Atrocity had some German songs, and I don't mean their bad 80s cover versions, and there is a lot of indie-alterna-stuff where the lyrics are actually better than the music - like Kettcar (formerly But Alive) or Muff Potter...again, this is really beyond metal.
