Remember when we used to have congregation picnics? Before they were "discouraged"?
Even as current as a year or two ago my family wasn't allowed to play worldly music over the sound system when doing hall cleaning.
This seems a lot like the expression of the tighter your grip the more sand that slips through your fingers. The rank and file want to be happy and normal and are pushing the envelope. The GB 2.0 has to be careful and strike some balance to allow expression like this while still maintaining overall control.
I could see some congregations falling down the slippery slope of expression and going too far and having the CO or higher come down on them.
