We saw Mike, a 25 year-old part-time charity worker and musician from Essex, on Saturday night's final audition show.
He said in the episode: "I love the show, I'm a fan of the show and it's always been a dream. I'm a part time musician and I want to be full time, I want it to be my life."
On The X Factor, Mike revealed how he started singing on YouTube and got as far as getting a Mobo nomination after releasing a single independently, quipping his claim to fame is losing to Adele.
Singing Alanis Morissette's Ironic in the audition room, Mike won praise from all four judges.
Simon Cowell said: "I like the fact you did something unusual with the track and I think what we're looking for on this show is someone who's prepared to take risks, combined with the fact I like your personality, that was a great audition."
But it was a VERY different story during Mike's first audition back in 2009.
While Louis Walsh and Cheryl Cole loved him, Mike was told by Simon: "My problem is you. I don't think you'll ever be good enough."
Speaking previously about the knockback, Mike said (via The Sun: “X Factor was an interesting journey… I got to the last stages of boot camp and Simon Cowell said I would never be good enough. So I thought: ‘Okay cool.’ I then went and worked for the Royal Bank Of Scotland for two years and then gave up my job and thought I need to focus on my music.
“I was living off like £30 a month and just using what I could and hustled myself.”
He went on: “I released my buzz single Hero a year later and it charted at 35 in the UK Independent chart and 88 in Top 100 and I signed a publishing deal.
“I’m out to prove Mr Cowell wrong.”
A source added to the newspaper this week: "Mike got through to bootcamp in 2009 and Simon’s comments motivated him to work harder and get better so he could go back to Simon and show him that he can do it.”
The X Factor continues this Saturday and Sunday night where Mike will battle it out for a place at judges' houses.
