Really current songs (=floor music versions thereof, of course) don't seem to be very common here, thank goodness..! We have ONE girl using a somewhat current song, but despite having two teen girls and spending a lot of time in the car it is one I had never heard played on the radio until last season was almost over. I didn't even know it was an actual song, lol, and that remains the one time I have heard it other than in the gym.
We hear enough of the popular pop songs at my other DDs dance competitions though.... if I never hear "shake it off" again I will be happy!!
