I think Cook and Mercado were the knock outs in round one.

Jason Castro gets soulful with "September Morn." It's palatable in an "easy listening radio" kind of way.

Jackson says "It was just ok."

"You need to get out of your comfort zone."

"We don't recognize you. You're not the person we put through to this competition," Cowell said. "There was no attempt to make the arrangement your own."

David Cook is looking more and more like the one to beat with "All I Really Need Is You."

"I'm a huge David Cook fan right now," Jackson says.

"I feel like I'm already looking at the American Idol," Abdul says.

"I thought the first song was ok and the second song was brilliant," Cowell said.
