The 13th Anthology

"The 13th Anthology" is one of four Kingdom Hearts tracks in the album Drammatica, a compilation of Yoko Shimomura's musical pieces from her works in various Square Enix games.

"The 13th Anthology" is essentially a compiled orchestration of the major pieces that represent Organization XIII throughout the series. These tracks all share at least a segment of the melody of "Another Side" and thus are included.
