Why isn't my furby 2012 dancing when i put on music?

Your Furby 2012 may not be dancing to music for a few reasons. First, ensure the volume is turned up and that the Furby's sensors are working properly; it needs to detect the music. Additionally, check if the Furby is in the correct mode, as it has different settings for play and music interaction. Lastly, ensure the music is loud enough for the Furby to respond.
