I was working on a little side startup that used crowdsourcing to help ID songs, I was just getting into researching how programs like shazam and midomi worked until I killed the project. His paper and the way it works is quite nice, but it's not perfect for other rare music and songs without elements that really stand out(frequencies or otherwise like house music). Thanks for the link!
