As usual, video link first:
Spotify as the biggest music app all around the world makes people very curious about the streaming of K-pop songs on this platform. According to the videos we can find out that to reach 100M streams on Spotify is way more harder than reach 100M views on YouTube for MOST of the K-pop artists (yes there's exception).
Of cause there's various reasons. Spotify has 320M active users now meanwhile YouTube has about 2B active users. The gap is kinda big... But anyway I think it's interesting to see how many songs on Spotify have more then 100M streams now and how many K-pop artists have reached this milestones. K-pop is still like a kid on Spotify so let's see how will it be in the future.
