Actually, I'm wondering that as well. I messaged Gigablah about the discography for Sonic Revolution and mentioned this duplicate I posted just awhile ago. I'm thinking SRRS-0007 is correct one since it's listed on Scinicade's website as that, but I tried searching up the catalog posted on the original entry prior to when it was added. I got a result from Scinicade's site except the link was dead and I just recently checked back to see if it's still the same but it's different.
It's listed as 'SORR-00007(SRRS-0007)' with SRRS-0007 being the actual catalog listed on the album. SORR-00000 I guess is just another catalog number to keep track of their releases under the circle in a consistent fashion. I own one of their albums and the catalog numbers seem to be accurate as listed on the website. I could just make a note of the other catalog number since it's not literally the actual one used when the album is distributed, though sometimes that's not the case as evident with their recent releases that have begun to use the other catalog number format.
