If it helps, it feels more like this was supposed to be a capstone for OSS and rerelease of the pre-existing songs (with some nice new songs that nonetheless are just closer looks at the timeline) than anything else. I too was dissappointed we didn't get any specific elaboration on the songs compared to the previous OSS albums, but I guess mothy's reaching a point where he can't afford to spoil anything else in this series via a mere album. 0O0/
