Anyone doing exercises by dancing?

I was using the just dance game for the wii for a while but now I'm using my own music on iPod now as it prefer my own music and I can dance any shape or form to it lol. I noticed I've been sweating a lot more doing it and getting more tired from it. It's quite enjoyable. And I've been losing weight doing it. Anyone else using same method and dancing their weight off? :)
