This is different to special or limited album, where both special and limited album were released for certain event like Christmas or group's anniversary. An example is Funky Town by T-ara, where this repackage album was released as the sequel of their previous EP, Black Eyes.
Unlike regular albums, special or limited editions are typically released for particular events such as Christmas or a band's anniversary. For instance, T-ara's "Funky Town" is a repackaged version of their earlier EP, "Black Eyes."
