Great Dance Song... Think it's from Sweden?

Hi Guys, just wondering if you could help me out, its a great tune, but cannot remember the name, or how it goes. It's got dancers dancing really provactively (I know that's not much help) and I think it's Swedish, pretty sure it was a huge hit so any help would be great, even if your not sure, just type it anyway, you could be right, cheers guys and girls :)
