MS vs MCW

Vatican II and Musicam Sacram (Adoremus Bulletin, November 2006).

"[Music in Catholic Worship], because it rejects the tradition of the sung Mass, cannot use a hierarchy that organically links the old with the new. Rather, it develops an entirely new hierarchy with regard to the relative importance of singing various parts of the Mass. This hierarchy lists in order: Acclamations, Processional Songs, the Responsorial Psalm, the Ordinary, Supplemental Songs, and Litanies. Such a hierarchy is a complete innovation with only a superficial link to any previous practice in the Church. MCW also focuses significantly on music that has no intrinsic relationship to the Mass. For example, it assumes that all of the Proper chants of the Mass will be replaced by hymns or songs."
