South Floridans Cristian Mauricio Escuti and German Schulz filed a suit on January 26, 2015 in Miami's US District Court claiming that this song rips off their original track, "Quiero Bailar Contigo." The plaintiffs stated that they recorded their tune on or about May 2009 and submitted a recording of their song to Sony/ATV three years later, but never heard back. However, Escuti and Schulz's case is not helped by the fact that "Bailando" was released by Republic, a company with no connection to Sony.
Here is a video
of Chayanne performing "Quiero Bailar Contigo." Do you think they are similar?
