The democratic and pedestrian character of the new Mass itself seems to invite the ditties that pass for hymns these days.
All you hear Catholics turning out these days are pop versions of the old Protestant anthems.
Even Catholic parishes today are not wanting for talent. But no serious singer or organist will get anywhere near the typical music program, at least if he wants to retain his self-respect.
But nowadays hymns are the norm, because people don't have much else to sing.
Participation is easily obtained with Latin chant.
