If something is my favourite song, I will listen it in the language where it is my favourite song. I generally don't have favourite songs in other languages.
I have ADHD. I struggle to concentrate on anything. I would rather have the ability to be distracted for a bit and still be able to follow the show, than have to rewind it constantly or force myself to concentrate on something (which my brain doesn't enjoy). I don't need a distraction from a boring show, I need something else to keep me engaged.
I'm not sure why you are putting infotainment youtube videos in their own category, I treat them just the same. If it has visuals that I want to see, I'll put it on my second monitor and watch it while I'm doing something else. Not while programming, because that requires its own focus, or a narrative game, but more a sandbox game like minecraft or factorio
Infotainment YouTube videos, and most YouTube videos in general, are just kind of mildly interesting or mildly entertaining content. Television shows are usually things production crews have toiled away at for years to complete an artistic vision. They're very different kinds of media.
It's like going to watch The Godfather in a movie theater and you scroll HN on your tablet the whole time during it.
I have severe ADHD as well and am distracted very easily and am constantly playing content while doing other things. But there's a difference between "content" and "art".
