Her musical style can be defined as the classical Spanish canción de autor or singer-songwriter, but it shows influences of Frank Sinatra, K's Choice and Los Planetas.

This was a smart move by the programme makers, as it introduced a further element of competition: contestants who sold more than 200,000 copies of their single won a recording contract for a debut album.

Vega's single was "Quiero Ser Tú" (I want to be you) – a bewitching, unusual and sophisticated track which she wrote herself – and it sold well enough to allow her to win her recording contract.

In 2006, after various wrangles with unsympathetic A&R in her new record company Universal Spain, Vega released her second album : Circular, with the first single being 'Una Vida Contigo' (A Life With You).

Her recording company then decided to re-release Circular with the subtitle "Como Girar Sin Dar La Vuelta" (How to go round without going back).
