Which Just Dance game features the song 'Gangnam Style' by Psy?

Just Dance 4 features PSY’s “Gangnam Style” as downloadable content.

Released in 2012, “Gangnam Style” became a worldwide phenomenon after its music video introduced PSY’s instantly recognizable horse-riding dance. Ubisoft brought that choreography to Just Dance 4 as a DLC routine rather than part of the game’s original on-disc soundtrack. The song’s availability date varied by platform and region, beginning in late 2012 and continuing into early 2013.

The game itself launched in October 2012 for Wii, Xbox 360, PlayStation 3, and later Wii U. Because “Gangnam Style” was released as DLC, some players remember it as belonging to later Just Dance titles, where it was reissued or made available through subscription services. Just Dance 2014 also carried the routine on some platforms, particularly because the newer consoles did not receive Just Dance 4.

The song is therefore most canonically associated with Just Dance 4’s DLC catalogue, even though it later appeared in other versions and services.
