Nah theyre both good tho
Don't listen to BTS as much (even tho I used to) but I still think their music is pretty good
Well I heard it's a pretty difficult language to learn so it's your decision really
As for your second question
Lemme put it that way, the only people NOT speaking English are 6 year olds and people over 70 (you literally learn English from 3rd grade on which is usually at 8 years old)
I had some old guy that was part of the crew when I went sailing for a week and he literally had this stereotypical extreme German accent that I always thought is exaggerated- but he DID speak English tho!
Also depends on the area tho
AND for example I visited The Hague and Amsterdam and most of the cashiers etc were talking English, like not even Dutch at first, just English
I'd say if you wanna come to Germany without knkwing German that shouldn't be much of a problem (except for maaaybe in Baverich- but idk if that's a stereotype or not tho)
Relatable except your list is longer I think
I speak German, English
Had French for three years and school but forgot 4/5 of it
Also randomly decided to tale duolingo courses on Japanese (yah still wanna finish that but no motivation)
Also on duolingo, Russian (also like three months ago for the last time tho)
I also know Latin (aka can translate it, not speak)
And I'm currently learning Dutch in school (since this year)
