AKP member idontsleep recently generated a file containing Gaon Digital Chart data from 2010 to present, taken directly from the official Gaon web site.
I was able to import the data into Excel, and the first thing I wanted to examine was the purported decline in Gaon points over the past few years (note: Gaon only started providing points in 2018).
Thus, for each week, I simply took the sum of Gaon points for each song in the top 100, and charted the results, as shown below:
As we can see, the decline is real, and it is significant.
The first thing I'll point out is that points tend to decline at the end of each year, due to the holidays of course.
However, we must note that total weekly points fell dramatically around the start of 2020 and never really recovered. I assume that this must be because of the COVID-19 pandemic. With people working from home and not going to school (and thus not commuting), it makes sense that music listening decreased.
What I'm more curious about is the noticeable fall in digital points starting in the middle of 2021, a decline that continues to this day. What do you think is causing this? The COVID-19 situation should be improving, which means that music consumption should be rising as people return to work and school.
Are people simply moving to different music platforms, ones that aren't part of Gaon data? I've read that YouTube Music (which isn't included in Gaon data) is gaining market share, so could that explain things? Are there any other possible explanations?
