The pair participated in a Ustream chat to preview songs from their debut collection Together, which is released in the UK today (September 24).
Jonathan Antoine described his life since leaving Britain's Got Talent as a "whirlwind" before they revealed which track fans voted as their favourite online.
The ten-track record features their own rendition of R.E.M's 'Everybody Hurts', a duet with Only Boys Aloud on 'The Prayer' and a cover of Take That's 'Rule The World'.
"This is one of our favourite songs," Jonathan Antoine previously said of the Gary Barlow-penned track. "When we first listened to the song after we had sung it in the studio we both thought this really has to be on the album.
"We had a real connection with this song. It's not just a love song. It's universal, everybody can take something from it and it reaches out to all."
Jonathan & Charlotte recently revealed that Simon Cowell apologised to them over their first audition, where he suggested dropping Charlotte Jaconelli from the lineup.
