Destra and AAC?
Australian IT reports that Destra is adding up to 30,000 tracks from Sony Music over the coming months.
Of interest, the article states that the songs will be available in both WMA and AAC formats. It goes on to specifically state that it will be compatible with the iPod.
Reportedly there will be "protection from copyright violation" built in. It isn't clear if the service would be offering the same FairPlay/AAC ("Protected AAC") files that are presently offered in Apple's iTunes Music Store.
