The basic technique they are using, to generate a Fourier transform and distinctive signature from a segment of music, and look it up in a hash, is completely obvious. It should not be patentable. The gory details of their algorithm might be patent worthy (although I don't like patents at all). But Roy did not use their algorithm, he invented something similar. Greedy trolls, hate. It might be a nice idea to integrate music identification with CDDB I think. Google has a similar system that they are using to prevent the use of copyright music in youtube clips (and they also have patents for their method). I suppose many other systems exist to do the same things. Roy should publish his code. Death to trolls.
