The X Factor finalist admitted that she refused to record material written for her as she wanted to create her own songs for new LP Heaven.
Ferguson is quoted by The Sun as saying: "[Syco] have been really brilliant – as soon as I put my foot down they back off completely. I just wanted songs I'd written on the album.
"At first I was going into sessions with writers who'd pretty much got all of the songs done already.
She added: "But I told management they needed to let me write it because otherwise no-one's going to think I'm a credible artist.
"Then they let me just go into sessions on my own – I couldn't believe it."
Ferguson's debut single 'Nothing's Real But Love' will be available to download on November 20, while her first album Heaven will follow a week later on December 5.
