The Pope thinks some Church music is terrible:
Certainly the meeting with modernity and the introduction of vernacular languages into the Liturgy has raised many problems: of musical languages, forms and genres. At times, a certain mediocrity, superficiality and banality have prevailed to the detriment of the beauty and intensity of the liturgical celebrations. That is why the various actors in this field, musicians and composers, conductors and singers in scholae cantorum, and those involved in the liturgy, can make a valuable contribution to the renewal —especially in quality — of sacred music and liturgical chant. To facilitate this process, we need to promote proper musical formation, also for those who are preparing to become priests, in dialogue with the musical trends of our time, with organizations representing the different cultural spheres, and with an ecumenical attitude.

In the US one of the main problems is that most of the songs sung seem to be locked in time in amber to the late sixties and the late seventies, usually coming from the wretched Saint Louis Jesuits. Go here for a good overview of the problem from 2009. Bad Church music is only a symptom of the willingness of too many Catholics to put up with junk that fastens like barnacles on the mass. Until the laity insists on better, nothing will be done.
