Kylie Minogue's hit single Can't Get You Out Of My Head was crowned the top tune of the Noughties today.
The song won first place in a poll of the most-played songs of the past decade.
The track was originally turned down by S Club 7 and Sophie Ellis-Bextor before Kylie used it.
The 2001 smash was followed by Britney Spears' Toxic in the survey by PRS (Performing Right Society) For Music, the UK's association of composers, songwriters and music publishers.
Both songs were the brainchild of songwriter Cathy Dennis, who worked with Robert Davis on Can't Get You Out Of My Head and Henrik Jonback, Pontus Winnberg and Christian Karlsson on Toxic.
Robbie Williams' biggest solo hit, Angels, was named the third most popular tune.
All of the top three songs won an Ivor Novello Award for Most Popular Song for the year they were released.
Scots band Wet Wet Wet were at number six with their version of the Troggs' Love Is All Around.
The 1994 hit was the soundtrack to Four Weddings And A Funeral and spent 15 weeks at the top of the UK charts.
PRS, which collects royalties on behalf of songwriters and composers, dipped into its records to work out which songs have been played and performed the most over the past 10 years.
Among them, the top five altogether have been played more than 875 million times over the decade.
The chart is based on airplay and live covers of the songs.
Guy Fletcher, PRS for Music chairman, said: "These are all classic songs of the Noughties and Can't Get You Out Of My Head is one of Kylie's all-time greatest hits.
"The writing talent behind this top five includes legends such as Cathy Dennis and Guy Chambers, and underpins the importance of good songwriting in producing a hit."
