What exactly are you talking about?
The video is from an American expat living in Germany with her family. Her video is originally in English.
YouTube started a feature where they auto translate videos to your assumed language. Might that be the case here?
I get mine usually at flea markets or second hand music shops in the next town over as I really love 80s rock and metal but you also get a ton of newish stuff.
Whenever I’m at a big electronics store like MediaMarkt in Germany they also still have CDs.
I also used sides like rebuy before, mainly for books and movies but I didn’t had a bad experience with that before.
Sometimes the bands themselves sell CDs on their fanshop.
There is no German text when I look at the OP.
