Is it intentional not to have South Korea represented? Considering the amount of music they produce and the global reach of Kpop shouldn't they be on the list?
Sorry for the confusion.
The Viral 50 and Global 50 charts show music that is currently popular in the countries that Spotify is available in. It is not to show popular music from the origin country where the music was made.
Spotify is currently not available in South Korea, so that is why there is not a chart for that country.
