What you linked me to is actually the re-release of GitS:SAC OST 1. I have the first pressing, without Rise and GET9 on it. What I'm referring to is the second soundtrack, which is pretty much music from 2nd GIG (including Rise and GET9), the second season of the series.
As for how the record store people are treating me, well, I shop at this little indie store in Seattle, and they're pretty snobby about the whole thing, like I'm some idiot who knows nothing about music and only buys whats cool. It's just funny, seeing how I saw Death Cab back in 1998 while they were in junior high school. Not a big deal or anything, just kinda odd.
