Vega did reasonably well in Operacion Triunfo, but was not one of the finalists. At the end of the series, each contestant not in the final was asked to release their own original 'single'. 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" - a bewitching, unusual and sophisticated track which she wrote herself - and it sold well enough to allow her to win her recording contract. The result, India, featured 11 self-written tracks, including covers of Frank Sinatra and K's Choice's. "Grita!" was the first single and was followed by "La verdad", which was a duet with Elena Gadel, also a contestant from Operacion Triunfo. Grita! reached number 1 in Spain, receiving airplay also in Belgium, Russia, and the United Kingdom. The last single was "Directo al Sol". The album contained a hidden track, "Mi Habitacion". India was one of the best-selling albums of 2004, and went Gold, largely due to its daring and original approach to songwriting and production: for instance, the title track is a 6 and a half minute piano and voice only; and the album's final track ends with Vega stringing lines from all the earlier tracks on the album into one exhilarating, extended riff. In 2006, after various wrangles with unsympathetic A&R in her new record companyUniversal Spain, Vega released her second album : Circular, with the first single being 'Una Vida Contigo'. All but one of the tracks were written by Vega. The album stalled at #40 in the Spanish charts, although the single received huge radio play. After a period of little activity, things began to pick up. 'Una Vida Contigo' earned Vega an "Autora Revelación a Los Premiosde la Musica" nomination. Her recording company then decided to re-release Circular with the subtitle "Como Girar Sin Dar La Vuelta". The release included two new songs, including the second single "Y Llueve.." and the song "Clave De Sol". The album also featured different artwork/graphics. Songs from the album are featured regularly on the Spanish TV version of Ugly Betty. Vega spent the first months of 2007 on a nationwide tour to support the new album. Her album, Metamorfosis, was released in 2009.
