When we were brainstorming to find a great rocker voice to make the list, the only name that immediately came to mind was David Cook. The American Idol season 7 winner doesn’t get the credit he deserves for his amazing range. Remember when he ripped the Andrew Lloyd Webber week on Idol? You ‘member, ‘member? He took what should have been the most difficult (and possibly boring) week and made it look like a cake walk, delivering a tear-inducing high note at the end of “Music of the Night” from Phantom of the Opera. Even if he wasn’t an overall brilliant singer, that note alone would have put him on the list.
