Yes, translating songs or poems is difficult. The Disney songs are usually translated quite well.
When you mentioned Bach, I had to remember Beethoven's "Ode to Joy"' I was curious about the English text, but that's not a translation, it's just a completely different text.
Too bad, you're cheated out of something wonderful. I love these lyrics.
But that's the exception to the rule that German is not a language well suited for singing.
