The idea behind "Speak in Tongues" is that a lot of Disney kisses are between lovers of differences, yet love unites them, in a way that is difficult to explain and sometimes impossible to understand... much like the religious meaning of "speaking in tongues" - communicating in a possesed manner. This can illustrate that love can be possessive, unclear, and confusing, but it has a power that can still bind people together, even if they are from different corners of the world.
