The OP asked why so many people are not interested in chazzunis.
Davening is not entertainment
“spiritual uplifting” comes from the spiritual effort of the Neshama to come close to Hashem, not from even heartfelt music. Davening is not music. im not certain that “cantors” understand what Davening is.
yes music is wonderful
yes music can uplift the spirit
yes they played music in the Bais HaMikdosh
but “cantorial” entertainment, though perhaps uplifting, is music. It is not Tefillah.
besides for the fact that it is a great Tirchah d’ Tzibur which is Assur.
“bringing the text of the Tefilla to life” is done in the soul, not in the ear.
so listen to your cantorial concerts at home on the CD, and be “uplifted” there.
not in the Holy Bais Knesses during Tefillah.
