Back at No. 1 for the 29th straight week, it’s everybody’s favorite ringtone. The music market tracker Billboard will begin ranking the customized mobile phone sound snippets beginning next week — another sign that ringtones are fast becoming a staple of recording industry sales.

As it does with other music sales data, Billboard will publish the top 20 ringtones purchased for each week. Included in the chart will be the song title, artist, previous week’s ranking and number of weeks on the chart.
