Trivia

 * This was revealed in the ESRB's rating summary. The following three lines are referenced as suggestive:
 * "Pop your Perignon"
 * "So let me get you/In your birthday suit"
 * "Boy when you're with me/I'll give you a taste"
 * "Pérignon" is a brand of champagne, "Birthday suit" refers to nudity, and "I'll give you a taste" refers to a French kiss. "Birthday suit" may not have been censored due to the "birthday" being titular.
 * This is the tenth song by Katy Perry song in the series. It is followed by Dark Horse and This Is How We Do.
 * This choreography reuses a move from Roar.
 * Also, the background dancers use a move from Pound The Alarm at some moments.
 * Just Dance 2015 came out in October, which is the same month as Katy Perry's birthday (Oct 25). The fact that this song by her is birthday themed will be featured makes it a huge coincidence. Not only this, but the game also came out just days before her birthday (either on October 21 or 23rd).
 * Unlike other dancers with makeup that is hardly visible in game, this dancer's makeup is clearly visible.
 * Birthday has a move similar to Primadonna. The move is that both coaches turn to each of their sides and "blow" the candles or chandeliers respectively.
 * This dancer's makeup scheme makes her face very visible, which is also happened to Break Free, Price Tag and Take On Me.
 * The coach's skirt sometimes gets in the way.
 * In the Party Master Mode, some pictograms for Jai Ho! (You Are My Destiny) and Boomsday are not synced with the dance moves.
 * The dancer lip syncs "Happy Birthday" every time the line is sung.
 * The Mashup for this song only features other songs by Katy Perry. The dancers for all the songs by Katy Perry, except Roar, are featured in the Mashup.
 * This is the first time a dancer from any non-Solo routine (in this case, a Trio) is used as a Solo dancer (the Dark Horse lead dancer).
 * Also, this is the only Just Dance 2015 Mashup that features at least one coach from every game of the main series.
 * When unlocking the avatar for this song after playing it, the lipstick is absent. However, when you look at it in the Avatar Shop, the lipstick appears.
 * This also happens with Cool For The Summer’s avatar on the seventh generation console versions of Just Dance 2016, as the collar is purple when unlocking it, while in the avatar shop, the avatar has a golden collar with spikes.
 * The first time Hot N Cold appears in the Mashup, the transition is not smooth like in other Mashups, but rather, it seems very sudden much like the transitions in Maneater’s Mashup.
 * There was a VIP on the World Dance Floor named Aurélie during most of November 2014. Players could dance with her while this song was played on the World Dance Floor.
 * In the preview video, the arrows for the pictograms were dark pink, despite the glove being red.
 * This song won in the Favorite Choreo category on the second Just Dance Awards.
 * In some beta gameplay snapshots, the coach appears to have a blue glow instead of a solid border like in the final version. In another, the coach's outline is orange instead of blue.
 * This is one of the songs selected for the Just Dance 2015 World Cup.undefined
 * The dancer was used as a promotional figure for E3.
 * Birthday was used by Just Dance to celebrate National Dessert Day 2015 on Twitter.undefined
 * The Classic routine is affected by a bug: sometimes, a black screen covers everything but the GUI.
 * As of June 3rd, 2016, the song is currently free on Just Dance Now due to Donut Day.
