Mashup

Dance Mashups are routines that consist of choreography from both previous Just Dance titles and those from the current game integrated into a single routine, first appeared in Just Dance 3. There were a lot of updates for the mode.

Description
Dance Mashups are routines that consist of dancers from previous Just Dance titles and the current game are all joined into one single routine, but not every dancer. There are two types of Mashups: regular and sweat. The original dancer from the song usually appears in the beginning and end of the routine, sometimes even during the middle of the song, if the song is '''Solo. If it's Duet or Dance Crew, a random Solo dancer takes the Duet's/Dance Crew's '''place; sometimes nothing replaces the dancers.

Just Dance 3
Just Dance 3 is the first game to have this mode. Here, there are three kinds of MashUps: Mashup, Duet Mashup and Sweat Mashup. Mashups and Duet Mashups have a kaleidoscopic background that can have different shapes and colors. Sweat Mashups have a gym as background.

Just Dance 2014
The background for Just Dance 2014's Normal and Sweat Mashups are very bright. There are dancers from previous games in the background, and the center of the "wheel" is a dome which looks like half a disco ball. The ground is full of slots where the current dancer dances on.

The Party Master Mode has bubbles behind a window in the background (and some of them have black silhouettes of dancers), and the selected dancer is standing on a platform.

Just Dance 2014 would only allow a small variety of dancers in the Mashups. Sweat Mashups returned and an upgraded version of Puppet Master Mode: Party Master Mode. From this game to now month Mashups are unlockable through the game

Trivia

 * In Just Dance 2, the mode "Medley" was supposed to be named Dance Mashups but was cut overall.
 * It returned in Just Dance 3 and was cut altogether in Just Dance 4, taking the place of Dance Mashups.
 * In Just Dance 4 Mashups, sometimes the dancers' reflections tend to exceed the boundaries.
 * Just Dance 4 's Mashup background was used for the extreme routines of Good Feeling and Run The Show.
 * In Just Dance 3 Sweat Mashups, the background contains a poster which shows the background from Sway (Quien Sera). Also, on Xbox, there is a big window, while on Wii and PS3, there is a mirror that reflects the coaches.
 * On the Wii version of Just Dance 2015, after playing a Mashup, the screen will flash a light blue for a split second before switching to the scoring screen.
 * In Just Dance 2015, a glitch will happen; when unlocking a monthly mashup, sometimes, you will lose 20 Mojo Coins, which is the amount of Mojo Coins that are required to unlock a Mojo Coin-unlockable Mashup. Plus, if you access the Mashup via the JD Wall, the game will freeze after a few minutes.
