The singer will release his first studio effort Believe in the UK on December 12, coinciding with his performance at this year's Royal Variety Performance.
McDowall will release his cover of U2's 'With Or Without You' as the lead single for the campaign, which heads up the LP's tracklist.
Speaking about his song choices for the album, the talent show champ explained: "I was brought up with a lot of country music like Kenny Rogers, but I've got quite eclectic tastes and have everything from Iron Maiden to Britney Spears on my iPod.
"I like a lot of R&B but I also love choral music. It kind of depends on my mood but I'm very open-minded about music."
The debut disc includes covers of tracks by Coldplay, Evanescence, Green Day and Josh Groban.
McDowall has also teamed up with Hayley Westenra for a rendition of 'The Prayer', which was famously recorded by Celine Dion and Andrea Bocelli.
"Instead of recording it in Italian we've done it in English," McDowall noted. "Hayley was a dream to work with and she's got such a beautiful voice."
The tracklist for Jai McDowall's Believe is as follows:
1. 'With Or Without You'
2. 'To Where You Are'
3. 'Fix You'
4. 'The Prayer'
5. 'How You Remind Me'
6. 'There You'll Be'
7. 'Feels Like Home'
8. 'Bring Me To Life'
9. 'Boulevard Of Broken Dreams'
10. 'One Day Like This'
