I think there's a loosely reliable english translation of the lyrics somewhere, I didn't get a chance to read over them though. And this is just my rambling, I did the same when Me!Me!Me! was still going full tilt and let's just say that my theories were small potatoes compared to the conspiracies given. I'm only loosely aware of some of the things going on in Japan that may have influenced the creators of the videos, but some of these guys I spoke to were able to pull out political intrigue, cultist imagery, and a clusterfuck more. They're crazy, obviously, but that doesn't mean they're wrong.
