Debuts in issue dated October 22.

The first Billboard chart tracking the hottest music downloads from around the world debuts in the issue dated October 22.

The new Euro Digital Tracks chart, Billboard's first benefit from Nielsen Music's new Nielsen SoundScan International platform, reflects a fast-growing market. From May 2 through Oct. 2, 17.1 million digital tracks were sold across Europe, with the United Kingdom accounting for more than 50% of those sales. In September alone, 3.8 million Pan-European digital tracks were sold.

Euro Digital Tracks will run weekly with data from 17 countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom) and 110 music download sites, including iTunes, CDON, Sony Connect and OD2, which includes affiliate data from MSN, Virgin, MTV, mycokemusic.com, Panasonic and Tiscali.

Nielsen's new World Digital Service tracks more than 130 music download sites from 19 countries. More than 110 of the sites are located outside of North America.

Nielsen SoundScan International expects to develop new charts that feature data from Japan and other Asian countries by the end of the year.
