Well, I don't have any links, but..
I've watched some pretty crazy Japanese music videos.
Happy Summer Wedding by Morning Musume.. man, what a mind job. It's like happy + 20. It's really crazy to watch.
I also remember this one music video Alanis Morsette had back when I was in grade 5 or so.. it was just her sitting in a dark room, the entire music video. I thought it was weird, and stupid.
