I think it must be said again, while there is clearly a place for hymns in our tradition, at the same time, what a momentous liturgical impact and appropriate liturgical spirit is set by use of the chanted propers of the Mass.
The Mass in its entirety may be watched by way of this Vatican television feed recording (and now also available on Gloria.tv), but here too are some videos that have been made available on Youtube.
Gradual/Alleluia Chant, Gospel and Homily
Homily and Creed (Credo III)
Prayers of the Faithful and Offertory
Canon Missae (in Latin)
The Communion
