Ella Eyre is a British singer whose appearance here comes with an unusual twist. She first broke through as a featured vocalist, lending her powerful voice to huge dance crossovers, and won a BRIT Critics' Choice nomination on the strength of that early promise. But as a lead artist, her streaming numbers concentrate on one track, and that track is a cover.
Her most-streamed song is a version of "We Don't Have to Take Our Clothes Off", originally a 1986 hit for Jermaine Stewart, which she recorded early in her career and which has since gone platinum in the UK.
On streaming, that cover sits near 397 million plays, while her next most-streamed track, "If I Go", trails at around 56 million. That puts the ratio above 7, past our 5.0 line.
So by our strict, numbers-only measure, Ella Eyre registers as a certified one-hit wonder, with the caveat noted clearly. As a guest vocalist she has been part of several enormous hits, and she has a respectable solo catalogue. It is simply that, under her own name, one reworking of an 80s classic has pulled far enough ahead of everything else to tip the maths.
