Trivia

 * All Calvin Harris dancers so far, are females.
 * However, this song contains a male sweat dancer.
 * The background is borrowed and recreated with a few different perks and colours from the Just Dance 4 exclusive song Domino.
 * The coach doesn't have the typical white skin tone, she's more like the coach of Hot n Cold but a little bit whiter.
 * This is the third Calvin Harris song in the series following Acceptable in the 80s and I Need Your Love (from Just Dance and Just Dance 2014 respectively).
 * Her skirt and the top of her hair can be seen through.
 * There is a Party Master Mode of this song on YouTube. However, The Wii U Gamepad was not seen.
 * In the second chorus, her skirt gets up because of the arm movement and shows the sequin.
 * In the game, the song is about 20 second shorter than the original one. The last chorus is just a bit cut.
 * In the trailer and first appearance of the song's pictograms were simpler and could be seen Gamescom with the most sophisticated pictograms.
 * This song's Puppet Master Mode features dance moves from some DLC's + Waking Up in Vegas and some from JD4.
 * Plus, Maneater's "Exorcise" was changed to "Dark Sun" while Cercavo Amore returned with "Opera Time".
 * Some of the dances from Just Dance 4 returned since their absence in Just Dance 2014
 * Feel This Moment, The Other Side, Wild, You Make Me Feel..., Gimme! Gimme! Gimme! (A Man After Midnight), and some DLC's from Just Dance 2014 first appeared in a party master in Just Dance 2015 since their absence in Just Dance 2014 but it's unknown if they'll appear in mash-ups.
 * The sweat dancer looks like the same dancer as Can't Hold Us,Just Dance (Song) sweat, Follow The Leader sweat, Love Me Again and the P1 from Blame It on the Boogie.
