I think with the flow of the album is just from the times we live in
artist sadly no longer make much money off albums since the rise of digital content. Artists get very little from that. They probably did most to what they would be best for profits over making it the best they can
Concerts and tours are were artist make money now. They really say if you want to support your artist nowadays, go to their show because they make money off that
To which ayu does very well with
iTunes killed the album business
PVs, singles and cms and all that were investments into the physical item, which now no longer makes nearly as much as they used too
