Like Mark Shea, I am no liturgical wit, nor claim to be. So when the Holy Father comes to town and celebrates Mass at the Nationals stadium, I will be delighted to hear the strains of Palestrina, Gregorian chant, or the Celtic alleluia. Being a convert not out of devotion to TLM, I, like my other Mass'keteer brothers, am the Pope's man. So sing and be joyful!
But if you want to do a little comparison shopping on melodies unto the Lord, the WaPo, surprisingly, has a very good piece here with Between Medieval And Folk, Two Mass Audiences, with a big hat tip to Amy Welborn.
