Which Just Dance game features the song 'Tik Tok' by Kesha?

The Just Dance game featuring Kesha's song “Tik Tok” is Just Dance 2.

Just Dance 2 is the second main installment in Ubisoft's rhythm-game series. It was released for the Wii in 2010 and expanded the original game's dance-focused format with a larger song list, additional modes, and multiplayer features. Kesha's “TiK ToK” appears among its featured tracks.

The song was a major pop hit before its appearance in the game. Released in 2009 as Kesha's debut solo single, it combines electropop and dance-pop production with a prominent handclap beat, synthesized sounds, and Auto-Tuned vocals. Its title is stylized as “TiK ToK,” although quiz references commonly write it as “Tik Tok.”

Players sometimes confuse the track with later Just Dance entries because songs and routines have been reused, remade, or made available through later catalog services. The original placement of Kesha's song, however, is Just Dance 2. The game’s track list contains 44 songs, and “TiK ToK” is one of its recognizable early-series selections.
