All-Stars: Play every song in the game with the score not being an issue.
5 Stars: Play every song in the game while also getting 5 stars in each song
Like in JD3 I believe that there should be an Individual Level “spreadsheet” type of leaderboard like in smash ultimate. This is because of the unique way the game handles sweat. I can link a Google doc which has what I think it should look like.
Dance Quests: You and three other people try to get all of the dance quests in the game (or at least you holding 4 Wiimotes and such) swapping the number of players as needed. All players must be named in the submission. Or maybe if that too unrealistic then just make it so you must get all the dance quests that are possible by one person
Collectables: only in JD3 and JD4 because of the way they handle collectibles is having this category justifiable from JD2014 onwards the mojo coins just don’t work for collectibles because you have to buy all the collectibles individually instead of unlocking them.
Dance Battles: Play every dance battle and win 5-0. The fun would come from trying your hardest to beat the AI perfectly.
I’m going to stop mentioning the non-stop pop category because it’s redundant at this point and every game from here on out has it from the start. I also didn’t mention it when talking about JD2 and JD3 because I simply forgot. However, JD4 is different because you have to unlock it first so I felt it worth mentioning.
