Vocally he got a voice on him. Love the duet with Ariana.

His problem will be how his team market him.
His niché are ballads as shows of his voice but commercially he don't quite have that as yet.

What Sam Smith did well was come out with dance/club popular tracks out the gate so his voice was relevant before we really saw him in person.
Set the tone for when we got to hear his 1st ballad
