Has Beyonce Infringed Choreographer’s Copyright in Dance Moves?

Accusations are flying around that the choreography for Beyoncé’s  new “Countdown” video were pilfered from the work of Belgian contemporary choreographer Anne Teresa De Keersmaeker.  There are some move -for-move/shot-for-shot similarities between the pieces. So, what is this, inspiration, homage or infringment? Beyonce takes her place in a long and distinguished line of dance plagerists. Stealing dance moves is nothing new.

Thoughts?
