Where the proper texts sung?
Did the form of the Ordinary texts conform to rubrics?
Did Latin make any appearance?
Did the musicians perform as if on a stage and elicit applause?
Where the people or God the focus of the liturgy?
Did the style draw mainly from secular culture or sacred forms?
Additionally, there's plenty of music that is theologically weak, questionable and even erroneous.
One Bread. One Body. Gentile or Jew.
Oh wait... what am I singing??!!
I can't take the three-ring circus around the Sacred Liturgy. For those of us who know what is happening and quite literally transport ourselves to the moments in the praetorium to the Resurrection, some of the antics going on are downright asinine.
Thankfully, the next generation of priests are being trained differently. Eventually, the jesters who are desperate for attention and place themselves in the Sanctuary to hijack the Liturgy will fade into oblivion.
