Which Just Dance game features the song 'Happy' by Pharrell Williams?

The Just Dance game featuring Pharrell Williams's “Happy” is Just Dance 2015.

“Happy” appears in the song list for Just Dance 2015, the 2014 entry in Ubisoft's dance series. The game was released for Wii, Wii U, PlayStation 3, PlayStation 4, Xbox 360, Xbox One, and other regional platforms. Its routines use the series' familiar on-screen choreography, with players following dancers and matching the movements.

Pharrell Williams wrote, produced, and performed “Happy.” The song was first associated with the 2013 animated film Despicable Me 2 and later became the lead single from Williams's 2014 studio album Girl. Its upbeat soul and pop sound made it especially suited to an accessible, family-friendly rhythm game.

The song is often dated to 2013 because that is when it first appeared with the film soundtrack, while Just Dance 2015 arrived the following year. That difference explains why the track can seem connected to either year. It is also easy to confuse the game title with the song's release year, but the Just Dance placement is specifically Just Dance 2015.
