Personal opinion, German is an ugly language, just my view. That maybe then reflected in the vocals, as i said earlier, i didn't realise how bad her voice was, but it was in German. Also i believe the words changed slightly in the two language versions. The German version was more serious, where the English version was more light hearted.
It's the one language i've always refused to learn, and the closest to English Language Tree... please log in to view this image
