Just Dance 2017/Beta Elements

Can't Feel My Face

 * Background was different.

Cake By The Ocean

 * In trailers for the game, there was a brief preview of the choreography that differed from the finalized version. The background behind the fish tank was a diner with tables, ketchup, and mustard bottles instead of a purple living room.
 * Two of the animals in the background also differed from the finalized version; the octopus was whiter and one of the seahorses had green arms instead of pink ones.

Don’t Stop Me Now

 * C2 was originally going to have a light blue outline like C1, as proven by some screenshots. In the final version of the routine, C2's beta outline was replaced by a paper-like outline.

September

 * September has a beta Gold Move which is seen in its gameplay preview.
 * In the gameplay video, September’s pictograms were lemon yellow, wine red and green instead of the in-game cobalt, light orange and fuchsia.

Watch Me (Whip/Nae Nae)

 * Before the song was announced, P3's outfit was darker.
 * Also before the song was announced, the pictograms were different colors, and there was a beta pictogram.

Worth It

 * In the song's album coach and coach selection image, the coach is seen with a yellow glove instead of a pink glove. Her outline is light blue in the E3 announcement trailer, and in the preview video and some screenshots, the pictogram color is light brown, but in the E3 demo, the pictograms are magenta.
