Chiefly produced by Brian Rawling and co-written by O'Meara, the album is a mix of contemporary pop, disco and soulful ballads.
[2] Caroline Sullivan from The Guardian found that "her solo album confirms beyond debate that [O'Meara] does indeed have a voice, and an Aguilera-type tornado at that, but it also proves that S Club's club-footed balladry still has a pernicious hold.
The Celine Dion-ised slurpiness of the opening title track kickstarts a whole album's worth of future hen party classics.
The joyous redemption of "Wish I Was Over You" is reminiscent of S Club's one claim to fabness, "Don't Stop Moving, and," similarly, just highlights the tepidness of the rest.
"[3] BBC Music's James Blake called Relentless "slick, well constructed and safer than a bet on black still being in fashion this time next year [...] However that doesn't detract from this being a fairly decent debut; far better than certain other ex boy and girl band members.
