James Arthur, who rose to fame after winning The X Factor, has said other male winners on the ITV talent show are not "believable" and look and sound "like puppets".
He also said he was not "in love" with his single You're Nobody 'til Somebody Loves You and felt his debut album had too many outside influences.
"For me, watching The X Factor over the years, they just haven't got it right.
The male winners that they've had, haven't been that believable," he said.
Speaking to Interia.tv in Poland, the musician said for the most part The X Factor has good intentions to find "real talent" but ends up getting "karaoke singers".
He added: "All they can do is try to make them look like good karaoke singers.
"You find the one or two amazing vocalists, like Leona Lewis, like Jennifer Hudson or Kelly Clarkson.
"It's really hard to find those types of singers. I honestly think you just hit the jackpot now and again. I think it's a lottery."
Since winning The X Factor in 2012, Arthur has released a self-titled debut album and headlined a European tour.
"I'm really just looking forward to my next record because although I thank my first album for what it's done for me, I feel a little bit detached from it now because it felt like there were so many influences on it," he said in the interview.
"I'd rather just be left alone to make my art and make my music," he added.
He is currently managed by Syco Music - Simon Cowell's record company.
"Now I have people telling me what I can and can't do, what music I can make, what music I can't make," he said.
"People that aren't artists don't think about creativity and art, they think about money.
"That's why when you 'find fame' or you get signed to a record label it's not what you imagined because what you imagine is they would just have 100% faith and trust in you in an artist and unfortunately that's not really the case.
"It's whatever sells," he added.
In an interview with the BBC to coincide with the album's November 2013 release date, Arthur said he was "proud" of his debut.
"I don't feel as though it sounds contrived or compromised, or overly produced or poppy or anything like that," he said.
"I feel like there's pop songs on there but they're really - I hate using the word credible now - but they're really authentic-sounding."
Last year the 26-year-old became involved in a Twitter row, after he was accused of using homophobic lyrics by celebrities including Matt Lucas and Frankie Boyle.
He later apologised for the slur.
