The silence from Apple is deafening.
It tells me a couple of things.
They feel they aren't ready for the load.
They found bugs in their audio recognition (Shazam) code that could be exploited.
More bugs with audio recognition only it is not recognizing obvious titles.
They are still waiting for some record company approval (highly doubt).
They should have open beta testing to more then a few Apple fanboys who pay to beta test.
