Having sold over 44 million records worldwide, had 14 number one singles and seven number one albums, Irish super-group Westlife celebrate over 14 years of success with the release of their Greatest Hits. With two Brits, an MTV Award, a World Music Award, no less than four Record of the Years under their belt and an incredible back catalogue spanning well over a decade not many artists can compare to Westlife's extraordinary success. In the UK alone they have earned the title of Biggest Selling International Band this Decade, scoring 10 multi platinum albums, the third highest number one single record in UK history (with only Elvis Presley and the Beatles ahead) and they also hold the crown for the Biggest Arena Act of All Time in the UK performing a record of 25 concerts at Wembley Arena.
