The song is upbeat and catchy and I can see why people like it and I have no propblem with having fun at the meeting, the problem I have is that I spent my life being told by these same people that emulating the worlds music and dance and showing outward emotion during worship or having musical services was wrong and is drawing attention to oneself rather than to Jehovah.
This is one step away from what you'd see at a church music service or a revival meeting. I'm sure the people feel great afterward but what about all the scriptures they used in the past to prove this kind of thing was improper?
I suppose if they can decide it's ok to use blood fractions after thousands who could have been saved by them died, this change in the music is pretty minor.
