AMERICAN IDOL

[SSKILLZ1]

By the way, what do you mean when you say “goggling”?

Sometime he gets a tone like he is singing underwater a little bit, his voice gets this strange tone, and than his voice breaks a bit as well, hence it give me like a goggling sound, ever try to talk with with water in your mouth, not that I would recommend as you liable to spit all over your self. LOL. But you will have a different sound.

The simple answer is his voice make a strange sound maybe it is unclear my analysis because I never heard anyone sound quite like that (It also has another negative outside of the sound makes him struggle with clarity), but it is clearly because his voice is damaged by singing metal. It is not his natural voice, he blew out his voice singing that way it is a shame. All is just my opinion of course.
