Closely associated with the Xenomania production house, since joining as their in-house drummer in 2008 she has played live and on record for popular artists such as Kylie Minogue, Girls Aloud and the Pet Shop Boys.

She has drawn positive reaction from the online music community for releasing her own material in collaboration with remixers such as Fred Falke for download without charge.

[2][3][4] She moved to London when she was 17 years old and gigged with several bands including Selfservice, who signed a development deal with songwriter Guy Chambers.

Xenomania producer Brian Higgins encouraged Florrie to sing one of the songs she had written, which prompted her to pursue her own music career.

She starred in the TV advert for the campaign performing a cover of Blondie's "Sunday Girl", and also featured in print advertisements shot by Ruven Afanador.

[21] Florrie told Ponystep magazine: I think it's really important to have that contact with fans and for them to be able to buy into your world or you as a person without any pressure from a corporation  ...

From 2019 to 2023, Arnold released a total of twelve singles, eleven of which would be part of Florrie's first compilation album title Personal, with the song "Butterfles" being left out of the project.

[41] In an interview with Ponystep, Florrie described her style as "a big mixture: Kind of a sixties, organic feel merged with modern pop beats and electronics".

[22] She also told Metro, "I grew up listening to my dad's Beatles records but I love electronic music, I like doing upbeat stuff to make people dance.

"[2] The Guardian writer Paul Lester said about Florrie that "she completely bypasses the sweaty authenticity of groaning determination for a slicker, brighter sort of pop desire.

[12] Time magazine wrote in 2014 that "Her brand of pop music is playful, propulsive, and built around rhythm, bearing the influence of her work as a session drummer for the songwriting/production squad Xenomania".

[42] After the release of her fourth EP, Sirens, Florrie met and began dating George Ezra with whom she was romantically involved for three years, until it was reported that they split up in early 2020.
