The 2010 X Factor winner listed Jackson's 'Man In The Mirror' as one of his six current iPod tunes of choice.
"Michael Jackson has been a massive musical inspiration," Cardle told Metro. "In my opinion he's the greatest singer to have ever walked the Earth.
"It's hard to pick an absolute favourite, but this song is definitely in the mix."
Cardle's other choices included his X Factor final duet partner Rihanna with 'What's My Name' and The Moody Blues' 'Nights In White Satin', which he also performed on the show.
Rounding out the six tracks were Beyoncé's 'Love On Top', Pearl Jam's 'Black' and Adele's 'Rolling In The Deep'.
Cardle said of performing 'Unfaithful' with Rihanna on the 2010 X Factor final: "Rihanna was super talented and super, super sexy.
"I had the honour of sharing the stage with her on The X Factor final and getting about as close as you can get with clothes on."
