Worldwide sales top 430M tracks.

The European version of iTunes Music Store has pushed past the 50 million paid-download milestone in its first year of operation, Apple Computer said today (June 23).

The computer giant simultaneously launched its market leading online music service last June in the United Kingdom, France and Germany. Apple has since rolled the download store out to a total of 17 European markets. Itunes also operates in the United States and Canada.

Since Apple pressed the button on its U.S. service in April 2003, it claims to have established a presence in 70% of the global music market. To date, roughly 430 million tracks have been downloaded on iTunes worldwide, according to Apple. The company did not break out sales figures by territory.

Apple has yet to confirm a launch date for imminent iTunes services in Japan and Australia.
