The seventh AKB48 album was announced in September 2015, during an event, and will be a special compilation to celebrate the tenth anniversary of the Japanese idol group and the departure, or "graduation" of long-time member and former AKB48 general director Minami Takahashi. The album was released in three versions: •
No. 1 Singles and
Million Singles are two-CD editions which compile all of the groups' singles that have reached the #1 position on the
Oricon charts plus three new tracks and all singles which have sold more than a million copies plus six new tracks respectively. •
Complete Singles is a three-CD bundle which includes every single released up to date (both indie singles "
Sakura no Hanabiratachi" and "
Skirt, Hirari" are presented in newly remixed versions) plus three new tracks and a bonus DVD. • The
Theater Edition features the same track list as
Million Singles with the exception of the last three tracks, which are replaced by two new songs by sub-units Tentoumu Chu! and Dendenmu Chu!. ==Track listing==
