Just Dance+ replaced Just Dance Unlimited starting with Just Dance 2023 Edition.
Just Dance Unlimited was the franchise’s subscription library from Just Dance 2016 through Just Dance 2022. It gave players access to hundreds of songs from earlier games and operated as an add-on to the annual releases.
Just Dance 2023 Edition changed the series to a live-service format, with annual song packs and continuing online updates. Alongside that shift, Ubisoft introduced Just Dance+, a new subscription service combining returning songs with tracks made exclusively for the service. It launched with about 150 songs.
A common mix-up is treating Just Dance+ as merely a renamed Unlimited subscription. The services serve similar purposes, but Just Dance+ belongs to the newer 2023 Edition platform and its successor editions, while Unlimited was the previous service. “Just Dance Now” is a separate mobile and streaming-based way to play, not the replacement service.
