I Transmigrated Wrong, But Not Entirely Wrong

Bang Dream: Mostly Old Bands, Especially Poppin'Party and the Original Seven Bands

Selection criteria: Mostly focused on the old seven-member group. The characters need to appear more often than the Chicken and Dog duo, roughly Old Group/35 > Chicken and Dog/10, though there may be some variation. Popularity and update speed don't affect eligibility. Books must reach a certain word count. Abandoned works are included too, though works featuring only the old group have no word-count requirement. If the list gets full, I may raise the requirements. I don't have time to guarantee
