Binary comparison won't work if the host has done any normalization,
compression, etc., so that leaves some kind of fuzzy comparison.
Usually, for music, that means a Fourier transform, but this is
admittedly beyond my ken.

The work done by http://echoprint.me/ might be of interest here. It's
a project to do music fingerprinting for applications like search. The
code generation portion of their software is MIT licensed.
