Aerosmith's Steven Tyler admitted that he didn't originally want the lucrative job as a judge on American Idol because he didn't think the contestants had genuine artistic integrity. 

Speaking to E! Online, he explained:

"I never wanted to do 'American Idol'. I turned around and said, 'The show sucks. How can kids be [an] American idol? They haven't played clubs, they haven't paid their dues, that haven't done what we did.' I was wrong. They are out there, we just have to wade through a bunch of them."

After taking up the position, he instantly became happy with his decision when finalist Lauren Alaina auditioned:

"When I first heard Lauren, seven months ago, it was the second city. You have to go through so many kids and she sang. She doesn't try to hit the notes, the words just go to that place. Everybody else is trying to hit the notes, and she's never had that problem with pitch."
