All 17 HKT singles and the main songs from their two albums! HKT has generally released less singles than the other sister groups. They've also went through a bunch of girls for the center position. Unlike Acchan, Jurina, Sayanee, or Yumirin who centered most singles in their respective groups, HKT has changed their center numerous times. Interestingly, their two most popular members very rarely got to be center. Sasshi was in a unique position where she was way too popular and Sakura was being given center positions in AKB instead.
