I am aware that 'SP' in the catalog no. does
not mean special... I'm certainly not ignorant, simply am pointing the possibility of the special edition being this "CSP/001" given the catalog no. on the back cover image provided. Clearly one can easily deduce the 'SP' stands for SPRIGGAN, more so taking the catalog no. for KIMERA as example.
As far as the special edition goes, ADV Films released in 2005 a 2disc special edition of SPRIGGAN, which included an expanded soundtrack, which I'm certain this "special edition" is from. The soundtrack with seemingly 20 tracks was released in 2003, so it makes sense this entry being the one enclosed with the 2disc special DVD.
Here's more info on it.
EDIT: SPRIGGAN Special Edition (2dics)
