Let's get metaphysical

The chorus of Pink's "God is a DJ":

If God is a DJ
Life is a dancefloor
Love is a rhythm
And you are the music

Okay, but who's doing the dancing? Is God playing to an empty house?

Later on Pink invites us to "get on the dancefloor" and "shake our ass," which suggests that we (the listeners) are at once the dancer and what is being danced to (the music). I'm no philosopher, but it seems to me that this conflation of cause (music) and effect (dancing), or of environment and individual, has inscrutably deep logical ramifications, possibly involving the collapse of the universe as we know it.
