Music mogul Simon Cowell credits his "incredibly juvenile taste" with making him so successful.

The American Idol judge believes he owes his current fame to a love of mainstream popular culture, and refusal to look down on chart music.

He says, "When you do this job, the one thing you can't do is guess what other people would like. You have to do things based on what you like.

"Luckily, I have incredibly juvenile taste at times and I also have very populist tastes.

"I've never been ashamed of popular culture. I don't like cultural snobbery and record companies are a hotbed of cultural snobs.

"I'm not making shows or records to be critically acclaimed. I want as many people as possible to buy my records and watch my TV shows. That is a buzz."
