Trivia

 * This is the fourth song by Britney Spears in the series, after Womanizer, Toxic and Baby One More Time . It is followed by Circus.
 * 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 routine has a lot of missing pictograms.
 * This is one of seven songs to appear twice or more in a row in a Mashup, along with Kids in America in Rock Lobster; The Power in (I've Had) The Time Of My Life; Beat Match Until I'm Blue in Oops!...I Did It Again; Dagomba and Crying Blood in Pump It; and Rockafeller Skank in Jamaican Dance.
 * When the cursor goes over the Mashup square in the Wii and Wii U menus, P3 appears in the character selection screen but is never featured in the Mashup.
 * This is the fourth cover by The Girly Team in the main series, following Fame (in Just Dance Now), Baby One More Time, Twist and Shake It, Ain't No Other Man, So Glamorous, Flashdance ... What A Feeling and Macarena.
 * 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.
 * This could most likely be a beta element.
 * Oops!...I Did It Again has a dance quest with the same requirement as Hit 'Em Up Style (Oops!).
 * In Just Dance Now, the background has many changes, including being more animated and having more particles during the bridge.
 * Also, at the end of the routine, when the black and white snapshot of the dancers is taken and displayed, their outlines and silhouettes are still visible. However, their outlines and silhouettes were not visible in Just Dance 4 when the snapshot was shown.
 * P2 is performed by Aurélie Sériné.
 * P4 is performed by Natsuko Ferguson.
