Let us be very clear on the purpose of this content. It is for the reluctant, or inexperienced, or not so confident language learner.
I agree with Edwin and Ed that this is not for the dedicated learner like them, or Ana, or me, who just wants to get at the language, who just jump right in and start swimming, no matter how strange it seems at first.
This is for the majority of learners who need to be guided gently until they have the confidence to swim on their own. I think that many learners will listen to these lessons only once per item, and eventually will want to listen to only the target language.
However, we are not getting the "average" learner at LingQ, and this is a way of making it easier for them, of leading them on to our way of learning, where only the target language is available.
