Randy Jackson has come out swinging against NBC's hit new singing competition 'The Voice,' after the latter show's coach Adam Levine took a potshot at 'American Idol.'

Jackson insists that 'The Voice' relies too much on a contrived premise. "It's a great thing when talent can be simple, honest and revered as opposed to spinning around with gimmicky chairs," Jackson tells The Hollywood Reporter. "Maybe Simon Cowell should have people opening doors. Like, 'Knock, knock. Who's singing? I can't see you!'"

The 'American Idol' judge's comments come after Levine belittled 'American idol' during an episode of 'The Voice.' When a contestant failed to win over any of the coaches, the Maroon 5 frontman remarked, "The people that we're not turning our chairs around for could win 'American Idol.'"

Jackson also cites 'American Idol''s longevity when comparing the two programs: "Look, none of these other shows could exist without somebody forging the path before them," he says. "I'm happy to say that 'Idol' did that and paved the way." He's also afraid that TV is getting overloaded with singing competitions. "My only fear with all these shows coming is that people don't tire of the format," warns Jackson.
