This song has been used in amateur videos by many.
I think, as was brought out, this is a reinvented WBTS, geared to try and keep the youth (a la LDS), as the older ones die off. And of course the plan is for this to go viral on youtube and wherever so as many people as possible will see it...including "worldly." Everything is exposed today including confidential BOE letters. Of course they anticipate this video to spread...I'm sure to combat the negativity out there about JW's.
It's a new day at the "house of god."
