The digital music market has more than tripled in a year, and that has helped offset a continuing decline in sales of CDs and other physical formats.
Spurred by the iPod revolution, digital music sales totaled $790 million in the first half of this year, equivalent to 6 percent of industry sales, the International
Federation of the Phonographic Industry estimated in a report Monday. That compared to $220 million in the same period last year.
