"American Idol" and the whole global merry-go-round of reality TV pop properties are more than just hit shows-- they're the largest and most public acts of rock criticism ever committed. They take the "everyone's a critic" truism and say, "Yes, and what's more, we trust you to be good critics on our terms-- to an extent." The show mixes a series of performances with a series of arguments-- amongst the judges, between judges and performers, between judges and the public, and across a million blogs, message boards, offices, and living rooms. All the arguments are about the same thing: What makes a star? Though after a while the question shifts to "what does it take to win 'Idol'?" which is a bit less interesting. And if you really want to narrow it down, the argument is simply: "What's the best way to get something tolerable out of Simon Cowell's definition of pop?"
Answering this question has led to some immense records-- "Since U Been Gone" is a lot of people's favorite pop single of the decade, and still has a gigantic impact on the kind of music new stars (not to mention Kelly Clarkson herself) are asked to make. But more commonly there's a weird disconnect between what reality TV produces and what's happening in the rest of pop. It's become a cliché to point out that Madonna would never have won "American Idol", but Cowellite icon Mariah wouldn't have either, at least judging by her street-smart, collaborative 00s output.
