JKT48 was scheduled to release its debut album in January 2013 , but production was hampered because of flooding in Jakarta . To celebrate the release , the group 's management team had distributed 100,000 free CD singles . Each single featured an Indonesian version of one of four songs : " Heavy Rotation " ; " Kimi no Koto ga Suki Dakara " ; " Baby ! Baby ! Baby ! " ; and " Ponytail to Shushu " . Members , some of whom had been directly affected by the flooding , later held a charity event in order to raise funds for the city 's relief efforts . The debut album , entitled '' Heavy Rotation '' , had a limited release at the JKT48 Theater on 16 February 2013 and went on sale in music stores nationwide on 2 March . All previously released singles were included in the album
