 At the start of her career , Diamandis was compared to other British female singer @-@ songwriters , with Paul Lester from The Guardian writing that she had a " zeitgeist @-@ y female essence " , although she took exception at such comparisons and said that all she shared with Kate Nash was " a vagina and a keyboard . " During the Electra Heart era , she called comparisons to Lady Gaga , Katy Perry and Lana Del Rey " really annoying " , preferring to be classed as herself . Her vocals have been compared to those of Karen O , Regina Spektor , Kate Bush , and Florence Welch , with an androgynous timbre akin to those of Annie Lennox and Heather Small . When reviewing The Family Jewels , Joe Copplestone from PopMatters noted that Diamandis 's vocal delivery occasionally overpowers the " inventive " melodies showcased in her songs .
