Heejun Han can't quite soar with 'Angels' on 'American Idol'

Heejun Han singing Robbie Williams' "Angels" on "American Idol" -- heartfelt and totally in control, with a joyful look on his face. Has got the audience swaying; shows off his soaring voice on the chorus.

He's my favorite contestant this year, but didn't think it was a great performance -- no emotional connection for me, kept waiting for something more.

"You have a voice that's smooth as silk; not sure it showed off how beautiful your voice is," says Jennifer Lopez.

"Not sure it was the right song," says Steven Tyler, but also still loves him. Randy Jackson agrees as well.
