Good question, John. Why bring up a pop/jazz singer on a folk/blues website to single him out for criticism?

But taking the original question/contention at face value, I would add that Michel Bublé's talent includes not only singing and at least some songwriting but instrumental skill as well. I know that he plays guitar - pretty decently at least. He may also play piano, but I'm not sure of that. He is also an actor. Even if he were only halfway decent at singing, songwriting, acting, and guitar playing, I'd say the total package amounts to a good deal of "talent."
