As a Catholic raised in the post-V2, Novus Ordo Church, I've come to accept a few common problems with the way the Mass is celebrated at many parishes. What follows is not necessarily specific to my parish:
I accept that the choir will sing with more enthusiasm than skill, and that the director will choose songs unfamiliar to us and just beyond the choir's ability. If I attend a folk Mass, I accept that the songs will be performed 4-8 bpm too slow, leading "Blessed Be the Lord" to sound like a dirge, and that at some point during the liturgical cycle "Lord of the Dance" will be played despite my most desperate pleas to God. If I attend the LifeTeen Mass, I accept that I will know none of the lyrics, and that the lead guitarist will rock the house whether rocking the Lord's house is appropriate or not.
