UK-based digital music operator OD2 has announced its own special event the day before Apple's music announcement.
OD2 is inviting selected media to a "major new announcement heralding a second generation of digital music services," on June 14. No additional information regarding the company's plans is available yet at this time.
The following day (June 15), Apple will make its own announcement. This seems likely to mark the launch of iTunes Music Store in Europe, though whether the service will be rolled out across the continent or on a territory-by-territory progression is not yet clear.
