Pinkie Pie is dancing to Stan Bush's song called "The Touch" m.youtube.com/watch?v=AZKpByV5… because she and her friends have power of harmony, to stand against all forces of evil and at other times not worry about the things they should not worry about: friendship or something. They have the touch. They have the power. They are the elements of harmony. I thought this song would be suitable for them, esp. for this particular pony [Pinkie Pie].
