Joshua Ledet blows them away with 'voice from another world' on 'American Idol'

Hits the high notes easily, has Randy Jackson shaking his head in disbelief. He could tour right now; it's the best performance of the night, gets the judges up on their feet. 

"This is what singing's about," exults Jackson, with Jennifer Lopez calling him "amazing," and adding, "that voice is from another world, you can do whatever you want. 

"You are the voice the world has been waiting to hear," says Steven Tyler. Judges are falling over themselves.

Humble Ledet says, "I just know the struggle my family's been through, I've been through, and I just hope to minister with my music."
