How many people on the Shazam team needed to come up with the fourier analysis? How big was the Shazam team? What did the rest of them do? This is my problem with only hiring comp-sci to build software and get stuff done. They all want to hire the John Carmacks of the world, but Doom would have never happened without John Romero. It's a waste of a PhD to spend it porting low level driver software from one architecture to another, but that type of work needs to be done, even by companies like Google.
