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 Just Dance 2017 files an unused file named "feedback_perfectplus.tape" can be found, which has an animation configuration similar to the one from Just Dance 2018's Perfect feedback. This animation was discarded for unknown reasons but later used in the next game.
In the files, there are four unreleased "Just Dance Machine" routines. They are:
There is an audio in the files called Amiibo but it was scrapped for unknown reasons, that would mean that Amiibo was going to be compatible with the game in Wii U, 3 avatars were found in the files of Link, Mario and Question Mark Block.
Unedited assets for most songs were found on Just Dance Unlimited servers.
Many of the video previews that were uploaded to the Just Dance Unlimited files when the game was released have early versions of the songs or different choreographies.
In a Just Dance Unlimited preview, the background uses different colors and animations, the pictures of the winking women were in full opacity and colored 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 preview gameplay for the Classic routine, the Gold Move pictogram did not have the thick orange outline that is seen in the final game.
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, because 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 color 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 mustaches were visible. In the final version, they are flesh-colored.

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 color 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.
The song was initially intended to be released in Just Dance 2017 for Wii U and Nintendo Switch with a different remake but was scrapped for unknown reasons. This is proven by a leaked video describing it planning to be released in the game and an avatar found in the files of Just Dance 2016.
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 color as their hair (making it invisible), their feet weren't faded and they had no outline.

There are some differences between the E3 gameplay and the final one:
In the E3 version of RADICAL, the routine starts with the sound at the beginning of each preview video. In the final version, it is replaced by a disco sound that gets louder.
Some pictograms look different, especially the one for Gold Move 1.
The end of the song sounds different as well.
Versions made after the E3 demo have the song name shown as RADICAL instead of "Radical".
The alternate version of "RADICAL" was originally a solo routine with an entirely different coach, choreography and background, but it was later replaced by the Helmet Version.
The Helmet Version's menu colors were orange and blue-grey instead of purple and light brown, and the coaches had a pink and fuchsia glove respectively instead of a light green and a magenta one. The menu banner is also different.

As seen in the E3 menu, September’s menu colors were light brown and gold instead of wine purple and orange.
In the gameplay video, September’s pictograms were lemon yellow, wine red and green instead of the in-game cobalt, light orange and fuchsia.
"September" has a Beta Gold Move, which is seen in its gameplay preview.
The Disco Fitness Version coach's belly warmer was much darker than in the final version. This Beta element appears in its Beta menu icon.
The routine's G2|jdu files also contain a different menu banner (showing the same background as the menu icon’s) and a different coach selection image.

In the demo, the lyrics color is carmine red. In the finalized version, it has been changed to yellow.
A different background with elements from the first pre-chorus was initially used as menu banner in the E3 version. However, the finalized menu banner uses elements from the verses.
The menu color was different as well, being purple instead of fire red.
The Extreme Version was meant to be a Trio of girls performing the official choreography of the song, but the idea did not make it into the final game for unknown reasons. An Autodance showing brief snippets of the unused routine can be found in the Just Dance Unlimited servers.

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 was light blue in the E3 announcement trailer but it 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.
