How does one look up what patents Shazam has? or is this a situation where it's possible but any patent worth a penny obfuscates the owner?

  Shazam has an Excellent patent. Very broad coverage. A lot harder and less effective using other means for this purpose. https://www.google.co.uk/patents/US6990453 https://www.google.co.uk/patents/US6990453

    A brief perusal, and that seems incredibly broad.
