I think the most important bit of yesterdays Apple announcement is the fact that Madonna’s complete work and Harry Potter audio books are sold exclusively on the iTunesMusicStore. It will make iTMS appealing to an even greater audience, locking its position as market leader. And of course it will increase Apple’s (iTMS’s) standing within the music industy. Madonna is exclusively on iTMS. It will prove as an example for other artists I am sure. First U2, now Madonna. Who’ll be next?
