He's just glad that it's such a leap beyond the inharmonic vocalization of hunger pains that you and your fave consider to be "singing."
I'm sure that every person on GAF would rather listen to Beyoncé's oft overdone chromatic runs than be subjected to Christina "taking it to church", as you and others like you tend to succinctly put it (it would be nice if your fave knew a thing or two about being succinct, but we can't have everything!).
Not fair to expect something of my fave that your own fave wouldn't know if it hit her upside the head.
