Apple Acquires Shazam

I still remember being at a WWDC Stump The Experts session where one of the first questions was what were the names of the songs playing before things kicked off, and a developer from Shazam stood up, and rattled all of them off.

There was a roar from the crowd, and he said he was from Shazam. And presumably all of us went and downloaded the app then and there.
