What I found on the IFPI codes of the non-promo cd:
IFPI L153 = Toshiba-EMI Ltd. Japan
IFPI 28R4 = also used on several Pink Floyd cds released in 2001 in Japan (Animals, released June 16, 2001 & A Collection Of Great Dance Songs, released May 25, 2001 & a few more), but also on a System F cd released in 2000.
Could this indicate this non-promo version of Siamese Dream was released in 2000 or 2001 too?
