I'm pretty sure this have been discussed before. But some recent certifications have made me realize more and more that the whole system doesn't make sense and, again, it just shows the lack of transparency we've been experiencing since gaon decided to hide the amount of downloads of every release. So, quick example: As most of you know, Bad Boy just received a download certification for surpassing 2,5 million downloads just a couple of hours ago. However, there's something missing for me. At gaon's 2018 yearly download chart these songs ranked in the following order: #18 - Red Velvet - Bad Boy #22 - TWICE - What is Love As of early 2019, Gaon confirmed that What is Love had an amount of 1,590,734 sales, as they won their respective SOTY award. So we can assume Red Velvet's Bad Boy wasn't really far from that as only 4 spots separate each one of them. I would guess around 1,7 million downloads, as Big Bang's Flower Road was confirmed to have 1,8 million and was positioned on 10th place. Also, WIL received a platinum streaming certification in November's last year. It's natural assuming that Twice is pretty big in terms of streamings, even for a song that wasn't that big when it came out. Now what is really bugging me is that in Gaon's 2019 download yearly chart, What is Love placed #166 and Bad Boy didn't chart in the top 200. Sure, we can expect that maybe the difference between the 166th place and the songs that are out of chart isn't that big and maybe with Psycho blowing out, maybe people started to download more Red Velvet songs during the last weeks of 2019 and first weeks of 2020. However, digging more in 가이섬.com (really helpful in these cases) i find out that during 2019 and 2020, Bad Boy didn't chart at all in gaon's weekly digital chart, hence why it didn't receive digital points for it's performance. On the other hand, during 2019 Twice's What is Love collected a very impressive amount of 102,734,800 digital points. Which is even more than Mamamoo's Starry Night during the same year. On top of that, Bad Boy still has not received a streaming certification, which is something natural to get first on most cases, even for groups as big as BTS. A similar thing happened with Blackpink's Forever Young a couple of months ago. It charted lower than BTS's Fake Love during 2018 and 2019's Gaon download chart and yet both songs achieved a download certification at the same time, last December. Even though it didn't receive a streaming certification first (something natural for a YG group, as you can even notice happened with DDDD). Is there any explanation for these cases? Am i missing something else? @Juanlag @acadz Please keep in mind that i'm not trying to shade any particular song or group in here. I'm just trying to be as neutral as possible to try to figure out what the hell happens with these damn certifications.
