Birthday

"Birthday" by Katy Perry is featured on Just Dance 2015. It was leaked on the ESRB website.

Trivia

 * This was revealed in the ESRB's rating summary. The following 3 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"
 * This will be the 11th Katy Perry song, and her second song in Just Dance 2015, after Dark Horse.
 * "Birthday" in "birthday suit" will probably be censored (despite the ESRB website fully saying it), as it was also removed in The Lazy Song.
