The world's first ringtones chart has been launched in the UK, and Eamon's I Don't Want You Back is at number one.
The list of the top 20 downloaded tunes is being put out every two weeks, with the information for the chart coming from mobile companies.
Eamon was followed in second place by D12's My Band. Eamon's ex, Frankee, only managed to get to six.
Most pop tunes are available for mobiles for up to £3.50, and about £70m of ringtones were sold in 2003.
