this kid is just sinply amazing, he has great talent. i really hope he can get into the music buisness because i would totally listen to him and buy all his songs! great singer!

His voice is more mature than justin bieber i think

I think that Justin Bieber is better. cuz Greyon is too yong and i think that Justin is more handsome.

he's good! has a good vocals.... almost like justin bieber, but younger, he's the new youtube sensation,.. and both of them are really good, don't have to compare the two of them,.. greyson is younger, and almost have better voice than justin have... he is breath taking!

He sort of sounds like a girl. But he's good.
