Does it makes sense, though that the translation itself would rhyme?

I don't think that is the translation of the song..
It would take a person great time and energy to create a lullaby that would rhyme when translated into another language as well as it's own.

I've been scouring for years for the translation to this song...

I'm not trying to discredit, but from a logical standpoint.. *shrugs* doesn't it seem like someone who knew the meaning of the song, simply wrote a poem about it?
