Even though he is president of their board and their publications carry his concordat, Archbishop Sample does not consider all of OCP's repertoire appropriate "liturgical music," particularly the diverse musical styles used at Sunday Mass.  He is a strong promoter of "traditional" hymnology, especially Latin chant.

Psalm 96 is an invitation to “Sing to the Lord a new song; sing to the Lord all you lands,” proclaiming God’s wondrous deeds of salvation. Psalm 149 is an exhortation to “Sing to the Lord a new song of praise in the assembly of the faithful,” celebrating victory over enemies. Both psalms call for “new songs.” As Wade Wisler, "both can be done well or badly."

Meanwhile, I'll join my voice with the psalmist and with contemporary composers declaring "all things are mine since I am His. How can I keep from singing?"
