All I can say is he tore up "First Time Ever I saw Your Face" I am hoping there is a studio version on youtube soon so I can record it. If you search youtube for the artist and add studio version you can usually find a full studio version of some of there song. David Atchuleta moves me emotionally but I don't want to listen to sad song that make me cry stuff all the time. David Cook would def be the more commercial choice in my opinion.

I did read where David A's bishop suggested that David singing to all these people in his carreer could be considered as service, so I wouldn't doubt he'd have a religious nature to the themes in his music.
