Eight of the top 10 ringtones are Christmas-related. They include Wizard's "Wish It Could Be Christmas Every Day" and Mariah Carey's "All I Want For Christmas."

The British ringtones market for 2004 was valued at £120 million ($231 million) in the Baskerville Mobile Music Report. The Official Ringtone Chart launched in June. It was spearheaded by the MEF and compiled by business advisory firm KPMG.
