The 26-year-old singer - real name Marina Diamandis - originally wanted to make a purely electronic album after her first record, 'The Family Jewels', but settled on the idea of making it bubblegum pop with a dark edge.
She said: ''I didn't feel a need to change, but it's a lot more electronic. The blueprint was a goth Britney Spears. I wanted to make a dark bubblegum pop album.
''The first song I wrote was called 'Living Dead' and the rest is a steady progression from there. The direction you go in isn't really calculated, it just happens - it's still pop.''
She told The Sun newspaper: ''I would be totally lying if I said it didn't annoy me to be compared to other artists. It really annoys me.
''I could draw up a list of about 30 artists I apparently sound like. From Lady Gaga to Katy Perry to Lana Del Rey. I don't know if it's because I'm versatile or because production affects how people judge music.''
