The 24-year-old singer - who triumphed on the ninth season of the Fox competition earlier this year - premiered 'Sweet Serendipity' on Ryan Seacrest's KIIS-FM show yesterday.
"The song is really about running into good lucky by accident," explained. "Things happen that you can't really control and positive things come from it.
"For me, that's really how my whole life has been; just things happening and going with the flow and making the best of everything that comes your way."
The former paint store worker also revealed that he had initially planned to release another track from his upcoming album Live It Up first but after listening to the record again he decided that this song "really stuck out".
"As time goes on and more songs come out and the album comes out, there is whole array of different sounds and songs and I felt that 'Sweet Serendipity' is one that everyone can get and grasp on to."
Live It Up will be released on November 16.
