How To Dance To "Gentleman" By PSY
PSY's single "Gentleman" has hit over a billion views, has got a much slower tempo than the cult-hit Gangnam Style, and the video plays on the same silliness formula too. So given the immense popularity of Gangnam Style, I expect it to get some decent airplay, making it a good practice song.
I think moves such as Rocking, The Easy Shift, and The Hesitation, and Sidesteps work, and would avoid faster house-style moves like The Club Walk. Ladies, most of the moves work, though I would avoid the Shakira hip moves.
Of course, the best part of the slower tempo is that it's a good song for grinding! Single guys, I recommend getting out of turn patterns as soon as possible, getting close, doing hip bumps for fun, and then transitioning to grinding!
