I got that shazam on my iphone and started right away with the most obscure songs I could think of, It gets the old flyingnun kiwi 80's stuff but it did not get Dr Demento Kinko the clown.
What I needed to know is HOW it matches so fast,one bit of a song across so many - its all here, the algorithm uses a spectral frequency fingerprint hash
"Big O 1" [constant time O(1)] which is why its so fast!
