American Idol:

For the finals, American Idol debuted a new state-of-the-art set and stage on March 11, 2008, along with a new on-air look. David Cook's performance of "Billie Jean" on top-ten night was lauded by the judges, but provoked controversy when they apparently mistook the Chris Cornell arrangement to be David Cook's own even though the performance was introduced as Cornell's version. Cornell himself said he was 'flattered' and praised David Cook's performance. David Cook was taken to the hospital after the top-nine performance show due to heart palpitations and high blood pressure.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Which arrangement was used for Cook's version of Billie Jean?
