The post above has articles supporting it so I don't see any reason to not believe it. The adjustments for downloads are down - me and some others who have followed the Gaon wondered what happened when one week this spring numbers suddenly jumped from a relatively low average (lower than last year because prices have doubled for subscription services) to again going above a million per week for top 10 artists. Was it a sale? Did they start cocunting differently? But then it lasted for months. Now they're back to the general area they were before and adjusted the figures in that window. Some wondered if, due to presentation mistakes on Gaon's behalf, streaming or other digital consumption was actually counted in the download numbers for that period.
