The soul singer said she didn't even own any of Springfield's music until a year ago and argued she was more influenced by male artists like Scott Walker and David Bowie.
She told the Daily Star: "I only got around to owning the Dusty Springfield box-set about a year ago. I just don’t relate to it. I don’t see how there’s a thread.
"It’s obviously an amazing honour to be compared to some of those really great artists, but the singers I’m obsessed with are David Bowie and Scott Walker.
"They’re the artists that have inspired me and made me alive. They almost make me cry with passion."
The Welsh singer also revealed that her number one single 'Mercy' was inspired by "sex".
She commented: "I have needs that music can’t meet. 'Mercy' is a song about sex...I’m blushing. I wanted something that was really liberating, and it helped me at that point vent some frustration."
