My Number One

Before Eurovision, ERT used an internal selection method to choose Paparizou. They chose her, and then had composers submit songs. They then picked four songs with Paparizou for her to sing at a Greek National Selection. At the Greek National Selection, Paparizou would have to sing the songs, and the public would vote via televoting to a special jury, that would determine what song to send to Eurovision. The songs to pick from were "My Number One", "OK", "Let's Get Wild" and "The Light in Our Soul". Shortly before the Greek national selection, it was revealed that "The Light in Our Soul" was released by the artist Big Alice in Germany, which broke the rules. The song was then disqualified from the selection process, leaving just three songs to select. The chorus of the winning track has already become a chant for AEK Athens supporters.

The voting to pick the song consisted of televoting, and a jury. Televoting held a 60% outcome to the song, and the jury held a 40% outcome. In the end, "My Number One" gained a combined 66.47% from televoting and jury votes, and was chosen to represent Greece in 2005 Eurovision Song Contest. Shortly after the song was picked, the music video was shot in just 1 day at the Thessaloniki Science Center and Technology Museum in Thessaloniki.

After the song was picked, Paparizou went on a European promotional tour. Paparizou visited over 20 countries on her tour, and sang on various TV shows, as well as gave many interviews. This method proved popular, and was used by many countries in 2006, including by Greece again in 2006.

As Greece had finished the 2004 Eurovision Song Contest in third place, the song was pre-qualified for the final in 2005. Thus, it was performed nineteenth on the night, following Croatia's Boris Novković and Lado with "Vukovi umiru sami" and preceding Russia's Natalia Podolskaya with "Nobody Hurt No One".

During the performance, Paparizou did a stage show of the song. Some of the best remembered visuals from the show include her dancing a traditional Greek Pontian dance, the 4 dancers making the shape on the number 1 of the floor (showed from aerial camera) and her playing an imaginary lyra while her dancers pick her up. At the close of voting, it had received 230 points, finishing at the head of a 24-strong field.

At the Congratulations special in late 2005, the song was named as one of the five greatest Contest entries of all time, earning the 4th place in ESC history.

"My Number One" also held 2 Eurovision records:

• The first one is that "My Number One" scored an average of only 6.05 points per jury, the lowest average for a winning song at the time. This record was previously held by Yugoslavia in 1989 with the song "Rock Me", and was later broken by Azerbaijan in 2011 with Running Scared, by Ell & Nikki.
• The second one "My Number One" held, was the record for most 12 points given out to one country. "My Number One" received 10 12 points, tying it with the UK's 1997 entry "Love Shine a Light" by Katrina and the Waves for the record (Televoting was only in place for 5 countries by 1997). This record was later broken by Fairytale, the winning song in 2009, which scored 16 12 points, and is currently held by the 2012 winner, Euphoria, which receive 18 sets of 12 points.

After Greece won Eurovision, a mass party started on the streets of Athens. People went out onto the streets with Greek flags, and started singing "My Number One", as well as honking car horns. This was similar to when Greece won Euro 2004, the 2005 Eurobasket title and when Greece won the silver medal in the 2006 FIBA World Championship. When Paparizou arrived back to Greece from Kyiv, mass crowds met her at the Athens International Airport, where she held up a Greek flag and the trophy.
