Old Mercedes Videos on Instagram

Has anyone else noticed that every video taken in period of an old Mercedes (i.e. old testing/manufacturing footage) is accompanied by either Cheri Cheri Lady or Brother Louis by Modern Talking? Is this a legal requirement now? Is Cheri Cheri Lady the new Dreamscape by 009 Sound System?

I now can't look at a picture of a W126 or W124 without one of those playing in my head!
