Germany and France are larger than the UK. Kpop is simply insignificant in Europe. The majority of Kpop listeners in Europe are teenage girls. But that's not a surprise, Kpop company don't try to do growth in Europe.
not you mentioning only france and germany as your argument.
europe is a continent of 40+contries, with god knows how many languages and cultures, the thing you all say white people don't have.
just take my country as an example:
200 km away from me is romania, a country of 20 million - i don't understand of a word of romanian;
200 km away is hungary, a country of 10 million, i also don't understand a word of hungarian;
340 km away is bulgaria, a country of 7 million, i understand maybe 20% of bulgarian
160 km away is bosnia and herzegovina, a country of 3,3 million, i understand 100% of their language
120 km is croatia, a country of 4 million, i understand 100 of croatian
300 km aways is macedonia, a country of 2 million, i understand 50% (i guess? perhaps less)
my country has a population of 7 million.
etc...
(bosnia, croatia, macedonia, and my country was once one country)
you get what I'm trying to say? those 7 mentioned countries have different cultures, different-ish languages, different tastes. all those countries combined have a population of 53 million people, less than both germany, and france alone. nobody's going to focus on europe as a whole because it's too much work and they would most certainly fail; what's popular in greece won't be popular in sweden or italia.

anyways. i think that list is more or less what we expected, i'm surprised korea is #6 tho
