Beyonce's number one hit Crazy In Love was the best-selling mobile phone
ringtone of 2003.
The chart smash easily beat dance tune Fly On The Wings Of Love by XTM. R Kelly's Ignition was next, followed by In Da Club by rapper 50 Cent.
R&B tunes were the most popular choice for ringtones last year, which reached record levels.
Black Eyed Peas' Where Is The Love?, the biggest single of 2003, also made the top 10, as did Clocks by Coldplay.
