Yeah, first they started increasing their sales x2 each release to almost sell 1M sales per album, and then all their old catalogue started shipping thousands of sales "somehow", we now confirm it was all a fraudulent scheme. And yes rv should have never crossed the 300K range, they have never been more popular or have a fandom as big as twice when they were selling 300k on 2018 and rv was selling 100k at the peak of their career, 300k-375k with the legal methods of boosting sales like lot of versions, digipacks, etc is the most I can believe from them, 990k sales for a red velvet album on 2022? No way.
this is so wrong.
this is the breakdown of their sales before their birthday album.
(2019) The ReVe Festival: Day 1 : 279k (2 versions)
(2019) The ReVe Festival: Day 2 : 239k (2 versions)
(2019) The ReVe Festival: Finale (compilation album) : 406k (2 versions)
(2021) Queendom : 396k (3 versions)
(2022) The ReVe Festival 2022 – Feel My Rhythm : 702k (3 versions)
(2022) The ReVe Festival 2022 – Birthday : 1,048k (17 versions)
all The ReVe Festival albums (day 1, 2, and finale) were released in 2019. that year was also the year they released Psycho (their biggest song). they also had hit song with Queendom in their next comeback. Feel My Rhythm was next huge hit from them. the anticipation from fans and non fans was very high after fell my rhythm, that's the reason why their next album in the same year was successful.
Birthday album is also their first album with more than 10 versions. before that they even sold 702k feel my rhythm album with only 3 versions.
