The March 2007 edition of Adoremus bulletin includes some interesting articles as usual, including a piece by Deacon Scott Haynes of the Society of St. John Cantius: To Give Glory to God.
A short excerpt:
"...a metanoia (“conversion”) is called for concerning liturgical music. To continue down the course of recent decades would be to stray from the “lineage of the great tradition of the past”, because the liturgical music in most parishes falls terribly short of the “simplicity, refinement and agility in form and rhythm” so characteristic of the chant and polyphony that the Church so highly lauds.
"But those restoring the heritage of Catholic music will encounter obstacles in the relativism and skepticism that are entrenched in the modern mindset."
