To this day there has never been any songs by Sophie-Ellis Bextor in any main Just Dance games’ base game, the only stuff there has been from her in the series is in fact her iconic Murder On The Dance Floor song in Just Dance+.  So not only should there start being Sophie Ellis-Bextor songs in Just Dance games somewhere down the line, but Murder On The Dance Floor should be featured in the base game of a main game as well.
