I was listening to Diva in my car one morning, on the way to work (oh yes, contrary to prejudices, this music help me wake up). And I thought 'would Shazam recognize also a particular voice singing opera?' It does, as you can see. Very useful for those who don't have much time googling. Just start it, let it do its job, then go to iTunes and download the entire album.
Shazam is available for any kind of mobile devices (for iPhones, it is available for free in the App store). It can recognize almost any tune coming from a recording.
Try §1 - correct answer
Try §2 - also correct
Try §3 was a challenge. I changed the CD :) But couldn't trick Shazam. It was its third right answer.
