Steve stormed to victory on the ITV talent show in 2004 after being mentored by Simon Cowell.
He bagged a '£1million record deal' and got a Number One single with a cover of 'Against All Odds', but some months later he parted from record label Sony BMG.
Since then, Steve has publicly spoken about his poor relationship with Simon and Sharon Osbourne, who was a judge at the time.
Steve told The Metro this week: "The show is about exploiting people's dreams, which is sad. But I suppose the producers who work on it might see it as helping people."
Steve, who said out of the 100,000 applying for the show, only "one or two" of them come out of it cheering, has opened up about his life before, during and after The X Factor in his new book, Getting Over The X.
The 46-year-old, who is working with his singer wife on new music, added: "The X Factor doesn't consume my life."
Speaking of his memoir, he said: "Maybe the book will touch those people - people who think, 'Let's see what might have happened if I'd won.' Maybe they'll think they had a lucky escape."
This weekend, Lauren Platt, Andrea Faustini, Ben Haenow and Fleur East will be competing in the semi-final. As the competition nears to an end, the singing hopefuls will be looking to secure a coveted spot in the final.
