Trivia

 * This is the fourth song by Britney Spears in the series, after Womanizer, Toxic and Baby One More Time.
 * This is the first time that a song in Just Dance 4 has a Mashup that only uses 1 dancer from that game; it is followed by Maneater, Can't Take My Eyes Off You, and the unused Istanbul (Not Constantinople).
 * However, Boom later became available as a DLC on Just Dance 4.
 * The normal routine has alot of missing pictograms.
 * In the Mashup, Beat Match Until I'm Blue appears twice in a row, separated by a transition.
 * This is the first of such an occurrence after Dagomba and Crying Blood 's two-in-a-row in Pump It 's Mashup.
 * When the Mashup is gone over on in the Wii and Wii U menus, P3 appears in the character selection screen but is never featured in the Mashup.
 * The unknown dancer in the Mashup is the same coach as the one in the ...Baby One More Time Mashup. Coincidentally, ...Baby One More Time is also a song by Britney Spears and yet covered by the same artist.
 * According to the chart in the background, each of the coaches are 6 feet (1.8m) tall. This makes them about the height of the average Dutch adult male, the tallest people in the world.
 * In the song's icon, P1's hair is longer than it is in the actual routine.
 * Oops!...I Did It Again has a dance quest with the same requirement as Hit 'Em Up Style (Oops!).
