The menu was a bit less equipped at first, as the Options section lacked the My Profile and the Search buttons.
The playlist names were all in caps, and there were also two unused ones named "MOST PLAYED" and "E3 SPECIALS".
On the PlayStation 4 version of the E3 copy, the X button was programmed to label the song as Favorite, and L1 was the button that one had to press to activate the dance routine. In the final version, the X button lets the player dance to the song instead of the L1 button.
There are some differences between the E3 and the Gamescom version of the Just Dance Machine animation:
The beginning is completely different.
The Story video is brighter and shorter.
The dancing emblem has a different animation.
The spaceship is darker and creates a much bigger and brighter light when it lands on the Earth.
A scene lasts longer where it starts off with a house dance party and about a minute the spaceship slowly comes down above the roof of the house.
However, in the Gamescom and Final release the scene is immediately shown when the spaceship abducts a dancer.
The man's silhouette is pink instead of black.
The routines' icons have different positions and the exclusive ones for Just Dance Unlimited are not shown at all.
An editing error from 0:58 to 1:03 (referring to the video comparison) is fixed.
At the end of the songlist, there was a button that would have activated the Non-Stop Shuffle mode from Just Dance 4. In the final version, it is replaced by the Playlist button.
In all the demo builds, the generic player nicknames ("Happy", "Jazzy", etc.) were in mixed case like in its two predecessors. In the final version, they are in all caps ("HAPPY" instead of "Happy"). Despite this, preview footage for newly-added Just Dance Unlimited routines would still have the names in mixed case.
When Superstar is achieved, the effects when you're getting closer to Superstar will still appear.
In the files, there are three unreleased Just Dance Machine. They are:
In a Beta Unlimited preview, the background uses different colors and animations, the pictures of the winking women were in full opacity and coloured and also the same place where the fingers had replaced the women in the final, and the lipsticks in the verses were placed horizontally and not vertically.
In trailers for the game, there was a very 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.
In the Beta menu icon for the Earphones Version, the wire for the earphones had an outline as well as the coaches. It has no outline in the final version.
In the E3 preview for the Classic routine, the pictograms are much lighter than in the final game. Their colors were changed after the routine was released in Just Dance Now, becuase of the mostly white background.
The Beta pictograms can also be seen in the Just Dance Now preview.
In the E3 menu, the Classic routine's menu colour is cyan instead of violet, and the menu banner is yellow instead of white.
In the initial menu icon for the Bollywood Version, P2's moustaches were visible. In the final version, they are flesh-coloured.

C2 was originally going to have a light blue outline like C1, as proven by some screenshots. It was also going to have a white outline, as seen on the square. In the final version of the routine, C2's beta outline was replaced by a paper-like outline.
In the preview gameplay at E3, the pictograms for C2 had the same colour as C1's. This was changed in the final version, where C2's pictograms are red instead of wine purple.
The Alternate coach was meant to have a blue, thin glow instead of a paper-like outline, as seen in its Beta menu icon.
An 8-bit remix of In the Hall of Mountain King was supposed to be in the game, but it was scrapped for unknown reasons. A very small part of the gameplay appears in the trailer of Just Dance 2017. The coach also appears in the behind scenes video shown during the Masterclass.
However, the song later made an official appearance in Just Dance 2018 with a remade routine and a remade dancer.
This song was supposed to be in the game covered, but it was scrapped for unknown reasons. A very small part of the gameplay appears in the trailer of Just Dance 2017.
However, the song later made an official appearance in Just Dance 2018 with a remade routine where a seahorse now takes the place of the original starfish dancer, and P1 from the original routine is now P2.
In its game files, it can be seen that no artist is credited, and the credit string reads "TBD" ("to be discussed") instead, which means the routine was scrapped in very early development.

In an early version of the routine, the background clones of the coach were totally different: their palette used shades of fuchsia instead of shades of blue, their skin had the same colour as their hair (making it invisible), their feet weren't faded and they had no outline.

In the song's album coach and coach selection image from the E3 demo, the coach is seen with a yellow glove instead of a pink glove, and the menu banner shows the two statues' heads instead of the columnate at the beginning of the routine.
The menu colors were different as well, as they were all in shades of light blue.
The lyrics were also different, being pink-gold instead of purple.
The coach's outline is light blue in the E3 announcement trailer but is magenta in the final game.
In the preview video and some screenshots, the pictogram color is light brown, but in the E3 demo and final game, the pictograms are magenta.

These skins were found in the files of Just Dance 2017 and for some reason were not used in the final version of the game; however, the Gear skin can appear when your actual skin is loading. The X skin appears when your skin can not be loaded.
