The author of the arrangement was credited, as has been stated previously. So I don't see the issue. The judges were talking about the performance, they were aware who did the arrangement. I agree that what made the song so awesome was David--his passion, boldness, powerful voice...wow. I enjoy watching and listening to him soooo much! Hello, All Right Now...they're all great.

David Cook is amazing! He has an amazing voice and is also a great performer. i love how he gets so into every song he performs. And he did credit Chris Cornell and Whitesnake with the versions he did. I found some other songs by him from his solo album he made prior to Idol. The album was called Analog Heart and from what i have heard of it....its very good.

He had me at "hello" ;-)

David Cook was the best last nights and the last few weeks... he's my fave since the auditions and this things about takin credit... he didnt and besides isnt that what all the contestants do? resing ppl's song? he just chooses the lesser known versions and he DOES credit the ppl what should be noted is that he did rocked last nite more than Chris's version and the judges said he's brave because he is ..for choosing the version that was lesser known to a remarkable popular POP song so that was huge to an audience that has no idea of a varyin version that was BRAVE and BOLD ...and he probably helped Chris get more downloads..

When I saw the David Cook's Billy Jean again on Video at http://idol-mania.com/american-idol-fan I was impressed. Some are sparking a controversy that David C ripped off musician Chris Cornell's version. Regardless David Cook was entertaining while David Archuleta's suck up to David Foster was just plain cheesy.
