If you're chilling in a Swedish and the music moves you, you'd better keep your feet still—Sweden's law against 'spontaneous dancing' in bars is still in place, and if the bar doesn't have a special license, you may be up for a fine, and the owner could lose his license.
The ban dates to the 1930s, when Swedish leaders of a different era were worried that dancing, drinking and decadence would corrupt Swedish youth. Even coffee was once banned in Sweden.
But times have changed, and four years ago, Parliament voted to ask the government to lift the ban. However, in the four years since nothing has changed. The Interior Minister, Mikael Darnberg has now told Parliament that the government is working on it, but is not being prioritized because they are busy working on laws to clamp down on organized crime and gang violence.
