I did not read this post as stone throwing but rather as a honest reaction by jroco to St. Sabina Christmas Eve celebration. While I personally don't agree with it, I certainly understand his reaction.

The focus of the mass is the Eucharist, it should not be an afterthought (or even an inconvenience) as it seemingly appears to be in the posted video. I agree with you that it is important that the laity be active participants in the mass and do not object to the use various forms of music that reflect the shared culture of the congregation but such use should deepen and draw one's attention to the Eucharist not be a distraction away from it.
