Antique disbanded in 2003, and Paparizou signed a solo recording contract with Sony Music, releasing the chart-topping debut single "Anapandites Kliseis" and album "Protereotita" (2004), with emphasis on laïko, pop, and dance sounds, but at first had modest sales. In 2005, she represented Greece in the Eurovision Song Contest with the song "My Number One", which she won. It was the first Greek win in the contest's history and transformed her career. Her album was subsequently certified double platinum by the International Federation of the Phonographic Industry of Greece. Paparizou attempted a career beyond Greece with English-language material, charting in a few countries abroad. Her three subsequent albums "Iparhi Logos" (2006), "The Game of Love" (2006) and "Vrisko To Logo Na Zo" (2008) all peaked at number one in Greece and reached platinum sales. Her fifth studio album "Giro Apo T' Oneiro" (2010) was also certified platinum. Paparizou's final release before she left Sony Music, "Greatest Hits & More", was released in 2011 and included "Baby It's Over", her biggest hit until 2016.
