So I've seen this pic around
And I just wanted to point out how confused people is with this. The number of users the apps have is pretty irrelevant, most of the streams keep coming from Melon. For songs to get the 100M certification in Circle they always need around 70M streams there so it means they still have around the 70% of the market share. If we followed what this graph shows Spotify would have more than a 10% of the streams Melon has, but they barely have 20 songs crossing 10k streams everyday, if we check Genie's numbers it's obvious they're not more than half of Melon's neither. If this chart were about streams and not users, Melon would have just around a 40-45% of the market share, it's really missleading. I'd be the first one having several of these apps if I lived in Korea to check stuff but I'd just pay the subscription for 1.
The only doubt I have is with Youtube music which is not included in Circle if I'm not wrong, but I'm still really iffy with this because I'm not sure if the system Youtube has is appropiated to be compared with other charts, and the difference between the amount of people having the app and the people actually using it could be huge because who doesn't have Youtube? You can have Youtube music just because you have Youtube and you want to have both, or it could even come installed in the smartphone.
