He definitely has the technical fundamentals down, no argument there. Nevertheless, his vocal timbre and overall style don't appeal to me; he sounds exactly like what he says he is: somebody with an average voice who learned to sing well. I can think of a half dozen really jaw-dropping vocalists--the people who make me rue my mediocre singing genes--who I am certain did not work nearly as hard or as long to get where they are, yet are in every way superior singers. Anyways, my only point is, yes, the deliberate practice meme is really hot right now, but natural talent still counts for a lot. This is especially true when it comes to singing, or anything that is governed by some physical property you were born with.
