Everywhere, the release date of the album is Nov 10, 2015...which i don't think is possible.
That date correspond to the release of the original game "Stardust Galaxy Warriors".
The game was then remade & ported to PS4 & Xbox One with the sub-title "Stellar Climax", and was released on Sep 9, 2016. The steam game was also updated but they kept the original date and the
original soundtrack (15 tracks).
This release have only 1 new track.
