It's SE-2075-2.
If you want Sumthing Else catalog numbers, the best source for them is the
Japanese online retailer HMV Online. Here's their SEMW album listing:
http://www.hmv.co.jp/search/index.as...MEL&category=1. If you view one of the album info pages, one of the fields is "カタログNo" followed by a four-digit number (it's right above "Sumthing Else/us"), that's the middle number of the catalog number. SEMW's catalog numbers are always SE-
xxxx-2, so you just fill the number in there and you've got the catalog number. The number on the
Uncharted 2 album page is 2075, and so we get SE-2075-2.
I think it was Blah that first discovered this? Or brought it to my attention, anyway.
