Just Dance Unlimited/Beta Elements

Graphics

 * As seen at E3, the songs weren't listed in alphabetical order.
 * In a beta screenshot, it can be seen that the service was supposed to have a "Favorites" section, similar to Just Dance Now. Additionally, Dark Horse was also seen in the Katy Perry playlist, despite not being featured in it in the final game. This was later added in Just Dance 2017.

Am I Wrong

 * Am I Wrong's coach was originally going to have a blue outline instead of a yellow one, as seen on the song's square and coach selection image.

Cake By The Ocean (VIPMADE)

 * In the menu icon, the cover and the Coach Selection Menu for the VIPMADE routine, Emrah and Joyce look completely different:
 * Emrah has a different haircut and wears a Yankee jacket instead of a T-shirt.
 * Joyce's hair is red and free instead of dark brown and tied up, and she wears a white dress instead of a tank top.

Cheerleader (Felix Jaehn Remix)

 * Cheerleader (Felix Jaehn Remix)'s preview shows placeholder pictogram colors. In the final version, the pictograms are colored Dark Pink, Light Pink, Green and Blue.
 * Additionally, the Gold Move pictograms did not have a gold aura around them.
 * The coaches had different colour palettes as well: they are shown on the Just Dance Unlimited promotional logo.

Je sais pas danser

 * Je sais pas danser was initially supposed to have a different menu icon.

She's Got Me Dancin'

 * Two pictograms from the Just Dance Now version were going to be used. They were later replaced by newly created ones.

YOUTH

 * The bubbles in the background were less animated and the wave pattern showing the title of the song is more transparent. These Beta elements are shown in the preview gameplay.
