Gangnam Style

"Gangnam Style" by PSY is featured as a DLC on Just Dance 4, Just Dance 2014 and Just Dance 2015, and on the main tracklist of Just Dance Wii U' and Just Dance Now'.

Background
The background changes a lot; when the male dancer (most likely PSY) has another male lay under his legs the background has horses like a carousel and at part of the song the background is yellow and has shadows. At one part of the routine, the background is a city with buildings. At other parts, there are silhouettes of dancers doing the dance behind a lime-yellow screen.

Gold Moves
There are 3 Gold Moves for this song:

Gold Moves 1 & 2: Point to the right when you and your partner are in the elevator position in the music video. Gold Move 3: Put your hand on your chin and lunge forward.

Trivia

 * Gangnam Style is the first PSY song in the Just Dance series; it is followed by Gentleman in Just Dance 2014.
 * This song is the second Korean song in the series, with the first being Bo Peep Bo Peep in Just Dance Wii 2.
 * However, this is the first song to sung in Korean, because the Japanese version of Bo Peep Bo Peep was used.
 * It's the first song that only one coach transforms in a duet. Second is Love Is All in Just Dance 2015.
 * P2, the first switched dancer, has two different avatars, one in the base game and one as a DLC (in JD2014, the original being in JD2015). The DLC version of the avatar has shorter and brighter hair, her glasses are slightly larger, and her hat is more curved.
 * This song has the most avatars (5, including the remade version of P2 Policewoman) for a single song in the entire series.
 * There are two unused gold moves. To get points with it, you have to shake your hands, in the beginning of the chorus; it has been removed.
 * Another one is a "Wave Gold Moves", where you have to put your hands behind your head. It is done from right to left.
 * The JDNow version had a totally different colour palette. If it was kept in the final game, it would be the first remake of a song which is already in HD.
 * It's the most played song in Just Dance Now.
