Clickie Clickie, oh-so Sugary

I'm living in China right now with a bunch of foreign students and my Japanese friend Midori loves this song....at first it's not that bad...but then it just keeps going. I honestly think this is one of the happiest songs I've ever heard.

So, CC, know any other ridiculously happy songs?
