Cyndi Lauper must have finally realized that her old hits are hipster dance mix staples. The So Unusual pop queen is showing that she’s hip to the mash-up fad by putting out a Japanese import single that combines her original claim to fame, “Girls Just Wanna Have Fun” with her much more recent release “Set Your Heart.” There’s no shame in admitting the sugary satisfaction tracks like this bring you; you know you’ve danced to it a hundred times.
