Da Xing's video: Sinobuz Kaiden clear

I know this isn't what I usually post, but I'm too proud not to. For those who don't know, I play a Japanese arcade game called beatmania iidx for a good 1.6 years now. In the game there are skill ranks that you can achieve. There is rank 1 up to 10, then there is one called chuuden, which is basically 11, and then there is kaiden, which is basically like grand master in tetris. The time it takes to go from never playing to rank 10, is about the same it takes to go from chuuden to kaiden. Being from the USA, achieving kaiden is a great feat, since it's a Japanese game, and not as popular over here, thus my inane reaction to clearing it.
